Inspire the Linear Power

500mA Positive Voltage Regulator

LM78MXX

Description

The Bay Linear LM78MXX is integrated linear positive regulator with three terminals. The LM78MXX offer several fixed output voltages making them useful in wide range of applications. When used as a zener diode/resistor combination replacement, the LM78MXX usually results in an effective output impedance improvement of two orders of magnitude, lower quiescent current.

The LM78MXX is available in the TO-220, TO-263 & TO-252 packages,

Features

•Output Current of 500mA

•Internal thermal overload protection

•Internal Short-Circuit Limited

•No External Component

•Output Voltage 5.0V, 6V, 8V, 9V, 10V, 12V, 15V

•Offer in plastic TO-220 & TO-252

•Direct Replacement for LM78MXX

Applications

•Post regulator for switching DC/DC converter

•Bias supply for analog circuits
