Inspire the Linear Power

1.00Amp High Current Low Dropout

B1129/B1129-3.3/B1129-5.0

Voltage Regulator Adjustable & Fix

Description

The Bay Linear B1129 is a 1 Amp high accuracy, low dropout

voltage regulator with only 40mV at light loads and

450mV(Typ.)@ 1.0A) and low quiescent current of 240µA typical.

Features

•

High output accuracy of 2% 3.3V & 5.0V

•

Output Adjustable from 1.24V to 26V

Output Current of 1.00A

Low Dropout Voltage

Low quiescent current

The B1129 is designed for low voltage a application that requires

lower dropout voltage and faster transient response. This device is

an excellent choice for use in powering low voltage applications

where require a lower dropout, faster transient response and as a

post regulator for switching supplies applications.

Extremely Tight Load & Line Regulation

Reverse-battery and “Load Dump” Protection

Zero Current Shutdown Mode (5-pin version)

Offer in TO-263, & SOT-223

•

Similar to industry Standard LT1129

The B1129 offers full protection against over-current faults,

reversed input polarity, reversed load insertion, and positive and

negative transient voltage. On-Chip trimming adjusts the reference

voltage to 1%. The B1129-xx devices are in 3 pin fixed voltage

Applications

regulators. The B1129 include an Enable pin in the 5 pin packages.

•

Powering VGA & Sound Card

LCD Monitor

The B1129are offered in a 3 & 5-pin SOT-223 & TO-263 package

compatible with other 3 terminal regulators. .
