Description
The Bay Linear B29150 is a 1.5A high accuracy, low dropout
voltage regulator with only 350mV(Typ.)@ 1.5A). The B29150 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 microprocessor that require
a lower dropout, faster transient response to regulate from +2.5V to
3.8V supplies and as a post regulator for switching supplies
applications.
The B29150 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%. Features such as Enable pin, Error Flag pin are also
included in the 5 pin packages
.
The B29150 is offer in a new LPDD
(Low Profile TO-263) package from 4.47 mm (DD) tickness down
to only 1.27 mm (LPDD) total tickness.
The B29150 are offered in a 3 & 5-pin TO-220 & TO-263 package
compatible with other 3 terminal regulators. For a 3A low dropout
regulator refer to the B39300 data sheet.
