B29150

Bay Bay Linear Ins Inspire the Linear Power 1.5A High Current Low Dropout Voltage Regulator Adjustable & Fix Output B29150 Preliminary Information 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.
