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
(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.

... Thermal Consideration Although the B29150/51/52/53 offers limiting circuitry for overload conditions necessary not to exceed the maximum junction temperature, and therefore to be careful about thermal resistance. The heat flow will follow the lowest resistance path, which is the Junction- to-case thermal resistance ...
