AZ78M05T - BCD Semiconductor

500mA 3-TERMINAL POSITIVE VOLTAGE REGULATOR AZ78MXX

Preliminary Datasheet

May 2005 Rev. 1. 0 BCD Semiconductor Manufacturing Limited

General Description

The AZ78MXX series are monolithic integrated cir-

cuits designed as fixed-voltage regulators for a wide

variety of applications including local, on-card regula-

tion.

This series of regulators are complete with internal

current limiting, thermal shutdown protection, and

safe-area compensation which make them virtually

immune from output overload. If adequate heat sink-

ing are provided, these regulators can deliver output

currents up to 0.5A.

The AZ78MXX series are available in two standard

plastic packages: TO-220 and TO-252.

Features

·Output Current up to 0.5A

·Fixed Outp ut Voltages o f 5V, 6V, 8V, 9V and 12V

·Output Voltage Tolerances of ±5% over the Ful l

Temperature Range

·Internal Short Circuit C urrent-Limiting

·Internal Thermal Overload Protection

Applications

·Consumer Electronics

·Microprocessor Power Supply

·Mother Board I/O Power Supply
