FUENTE ESTABILIZADA DE 2 A 30V 5A
FUNCIONAMIENTO El transformador se conecta en la entrada de CA reduciendo la tensión de la línea de 110 Vca a 24 Vac. Esta tensión es rectificada por los 4 diodos rectificadores D1 a D4 (P600), que están conectados en configuración puente. Por medio del capacitor de 3300uF/40V se filtra esta tensión para obtener una tensión prácticamente continua. Esto sucede ya que durante el período ascendente del pulso el capacitor se carga y cuando llega el pulso descendente comienza a descargarse, pero como el período de tiempo es muy corto y el capacitor tiene una capacidad elevada el mismo se descargará muy poco. El condensador C2, lleva las frecuencias elevadas a tierra de manera que exista una entrada lo mas “limpia” posible al regulador de voltaje LM317. La salida de voltaje se ajusta mediante P1 de 5K. El capacitor C3 mejora la estabilidad de la tensión de salida. Como el LM317 no puede proporcionar una corriente alta, el circuito incluye dos transistores de potencia Q2 y Q3 montados en paralelo para mayor disipación. Estos transistores están a su vez controlados por Q1 que recibe la salida del regulador LM317. Las resistencias R3 y R4 están montadas en paralelo y sirven para polarizar las bases de Q2 y Q3. A la salida, dos condensadores, C4(Poliester) y C5(Electrolitico) bloquean cualquier influencia de alta frecuencia que pueda proceder de la propia carga.

OUTPUT VOLTAGE RANGE: 1.2 TO 37V OUTPUT CURRENT IN EXCESS OF 1.5A 0.1% LINE AND LOAD REGULATION FLOATING OPERATION FOR HIGH VOLTAGES COMPLETE SERIES OF PROTECTIONS: CURRENT LIMITING, THERMAL SHUTDOWN AND SOA CONTROL
DESCRIPTION The LM117/LM217/LM317 are monolithic integrated circuit in TO-220, TO-220FP, TO-3 and D2PAK packages intended for use as positive adjustable voltage regulators. They are designed to supply more than 1.5A of load current with an output voltage adjustable over a 1.2 to 37V range. The nominal output voltage is selected by means of only a resistive divider, making the device exceptionally easy to use and eliminating the stocking of many fixed regulators.

Figure 7: Basic Adjustable Regulator
APPLICATION INFORMATION The LM117/217/317 provides an internal reference voltage of 1.25V between the output and adjustments terminals. This is used to set a constant current flow across an external resistor divider (see fig. 4), giving an output voltage VO of: VO = VREF (1 + R2/R1) + IADJ R2 The device was designed to minimize the term IADJ (100µA max) and to maintain it very constant with line and load changes. Usually, the error term IADJ × R2 can be neglected. To obtain the previous requirement, all the regulator quiescent current is returned to the output terminal, imposing a minimum load current condition. If the load is insufficient, the output voltage will rise. Since the LM117/217317 is a floating regulator and "sees" only the input-to-output differential voltage, supplies of very high voltage with respect to ground can be regulated as long as the maximum input-to-output differential is not exceeded. Furthermore, programmable regulator are easily obtainable and, by connecting a fixed resistor between the adjustment and output, the device can be used as a precision current regulator. In order to optimize the load regulation, the current set resistor R1 (see fig. 4) should be tied as close as possible to the regulator, while the ground terminal of R2 should be near the ground of the load to provide remote ground sensing. Performance may be improved with added capacitance as follow: An input by capacitor of 0.1µF An adjustment terminal to ground 10µF capacitor to improve the ripple rejection of about 15 dB (CADJ). An 1µF tantalum (or 25µFAluminium electrolytic) capacitor on the output to improve transient response. In additional to external capacitors, it is good practice to add protection diodes, as shown in fig.5. D1 protect the device against input short circuit, while D2 protect against output short circuit for capacitance discharging. 5/15

FUNCIONAMIENTO El transformador se conecta en la entrada de CA reduciendo la tensión de la línea de 110 Vca a 24 Vac. Esta tensión es rectificada por los 4 diodos rectificadores D1 a D4 (P600), que están conectados en configuración puente. Por medio del capacitor de 3300uF/40V se filtra esta tensión para obtener una tensión prácticamente continua. Esto sucede ya que durante el período ascendente del pulso el capacitor se carga y cuando llega el pulso descendente comienza a descargarse, pero como el período de tiempo es muy corto y el capacitor tiene una capacidad elevada el mismo se descargará muy poco. El condensador C2, lleva las frecuencias elevadas a tierra de manera que exista una entrada lo mas “limpia” posible al regulador de voltaje LM317. La salida de voltaje se ajusta mediante P1 de 5K. El capacitor C3 mejora la estabilidad de la tensión de salida. Como el LM317 no puede proporcionar una corriente alta, el circuito incluye dos transistores de potencia Q2 y Q3 montados en paralelo para mayor disipación. Estos transistores están a su vez controlados por Q1 que recibe la salida del regulador LM317. Las resistencias R3 y R4 están montadas en paralelo y sirven para polarizar las bases de Q2 y Q3. A la salida, dos condensadores, C4(Poliester) y C5(Electrolitico) bloquean cualquier influencia de alta frecuencia que pueda proceder de la propia carga.

DESCRIPTION The LM117/LM217/LM317 are monolithic integrated circuit in TO-220, TO-220FP, TO-3 and D2PAK packages intended for use as positive adjustable voltage regulators. They are designed to supply more than 1.5A of load current with an output voltage adjustable over a 1.2 to 37V range. The nominal output voltage is selected by means of only a resistive divider, making the device exceptionally easy to use and eliminating the stocking of many fixed regulators.

Figure 7: Basic Adjustable Regulator
APPLICATION INFORMATION The LM117/217/317 provides an internal reference voltage of 1.25V between the output and adjustments terminals. This is used to set a constant current flow across an external resistor divider (see fig. 4), giving an output voltage VO of: VO = VREF (1 + R2/R1) + IADJ R2 The device was designed to minimize the term IADJ (100µA max) and to maintain it very constant with line and load changes. Usually, the error term IADJ × R2 can be neglected. To obtain the previous requirement, all the regulator quiescent current is returned to the output terminal, imposing a minimum load current condition. If the load is insufficient, the output voltage will rise. Since the LM117/217317 is a floating regulator and "sees" only the input-to-output differential voltage, supplies of very high voltage with respect to ground can be regulated as long as the maximum input-to-output differential is not exceeded. Furthermore, programmable regulator are easily obtainable and, by connecting a fixed resistor between the adjustment and output, the device can be used as a precision current regulator. In order to optimize the load regulation, the current set resistor R1 (see fig. 4) should be tied as close as possible to the regulator, while the ground terminal of R2 should be near the ground of the load to provide remote ground sensing. Performance may be improved with added capacitance as follow: An input by capacitor of 0.1µF An adjustment terminal to ground 10µF capacitor to improve the ripple rejection of about 15 dB (CADJ). An 1µF tantalum (or 25µFAluminium electrolytic) capacitor on the output to improve transient response. In additional to external capacitors, it is good practice to add protection diodes, as shown in fig.5. D1 protect the device against input short circuit, while D2 protect against output short circuit for capacitance discharging. 5/15
