1.5A Positive Voltage Regulator		LM78XX

Description

The Bay Linear LM78XX is integrated linear positive regulator with three terminals. The LM78XX offer several fixed output voltages making them useful in wide range of applications. When used as a zener diode/resistor combination replacement, the LM78XX usually results in an effective output impedance improvement of two orders of magnitude, lower quiescent current.

The LM78XX is available in the TO-252, TO-220 & TO-263 packages,

Features

•Output Current of 1.5A

•Output Voltage Tolerance of 5%

•Internal thermal overload protection

•Internal Short-Circuit Limited

•No External Component

•Output Voltage 5.0V, 6V, 8V, 9V, 10V, 12V, 15V, 18V, 24V

•Offer in plastic TO-252, TO-220 & TO-263

•Direct Replacement for LM78XX

Applications
