IC Voltage Regulator and DC Power Supply Circuits

Objectives

To understand the theory, analysis, and design concepts of lC voltage regulator circuits:

  • Voltage regulator fundamental concepts using discrete devices.
  • Working knowledge with three-terminal IC voltage regulators.
  • Working principles of special voltage regulator ICs.
  • Working principles of precision voltage regulator to minimize limitations of three-terminal IC voltage regulators.
  • The concept of SMPS using PWM to produce constant DC.
8.1 INTRODUCTION

Direct current (DC) power supply circuits for electronic systems use unregulated DC voltage as input voltage from rectifier circuits and process them through voltage regulator circuits to obtain regulated DC output voltages of desired ...
