1. INTRODUCTION

NEC produces a variety of ICs for power supplies that differ in their on-chip functions and usage. Within these,

large quantities of three-terminal regulators have come to be used to configure stabilized power supplies easily using

few external components.

However, the occurrence of unexpected irregularities when designing power supply circuits also has increased.

Therefore, this manual starts with the basic structure of the main bipolar process that is used in ICs for power

supplies and gives precautions pertaining to actual applications.

2. BASIC STRUCTURE OF A POWER SUPPLY IC

As mentioned in chapter 1, a power supply IC mainly uses a bipolar process. Understanding the structure of an

IC that uses a bipolar process also is useful for applications.

2.1 Structure of a Bipolar IC

The following elements can be made into an IC in a general bipolar process.

NPN transistor

PNP transistor

Resistor

Capacitor

Figures 2-1 through 2-3 show the structure of each.
