LTspice - LM317 Voltage Regulator Design & Simulation

 Hello Reader,

This article is very useful for those who are persuing the career in Electronics Circuit Design.

LM317 is 3 terminal device which can be used to power up small loads up to 1.5A.

Below is the features of LM317.

1• Output voltage range adjustable

from 1.25 V to 37 V

• Output current greater than 1.5 A

• Internal short-circuit current limiting

• Thermal overload protection

• Output safe-area compensation

VO is calculated as shown below. IADJ is typically 50 µA and negligible in most applications.

VO = VREF (1 + R2 / R1) + (IADJ × R2)

Please watch below video to understand circuit design & Simulation.

Op-Amp Shunt Voltage Regulator Design Fig.1 In this blog i will be explaining about the design of a Opamp shunt voltage regulator. Pros and Cons of the shunt voltage regulator will be discussed. The complete explanation can be watched in video below. Working :  Due to variation in input voltage Vin or load current IL there is a change in output voltage of shunt regulator. Terminology Used : Vin = Input Voltage Vo =Output Voltage Vz = Fixed Reference Voltage R1 & R2 = Sample or Voltage monitoring Circuit Opamp- Error Amplifier Rs = Input Current Limiting resistor Vs = Voltage across Rs Transistor = It is used to regulator the output voltage RL = Load Resistance IL = Load current Is = Source Current Ic = Transistor collector current V+ = Voltage at Non Inverting Terminal V- = Voltage at Inverting Terminal Case 1: If the output voltage increases due to sudden change in input voltage or load current. Since sample circuit monitor the output voltage using voltage divider R1 and R2. The V
