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 240
μ
A typical.
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.
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
regulators. The B1129 include an Enable pin in the 5 pin packages
.
The B1129are offered in a 3 & 5-pin SOT-223 & TO-263 package
compatible with other 3 terminal regulators. .
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
Extremely Tight Load & Line Regulation
Reverse-battery and “Load Dump” Protection
Zero Current Shutdown Mode (5-pin version)
Offer in TO-263, & SOT-223
