M29150A/B
LINEAR INTEGRATED CIRCUIT
1.5A, VERY LOW DROP
VOLTAGE REGULATORS
„
DESCRIPTION
As the UTC linear integrated LDO, the UTC M29150A/B shows
a high current, high accuracy, low-dropout voltage. The features are:
400mV dropout voltage, very low ground current. Cause the series
have been designed for high current loads, so they are also used in
lower current, extremely low dropout-critical systems (in which their
tiny dropout voltage and ground current values are important
attributes).
„
FEATURES
* Very low dropout voltage : typ. [email protected]=1.5A
* Output current guaranteed 1.5A
* Fixed and adjustable output voltage
* Thermal limit and Internal current
* Logic controlled electronic shutdown available
* Over voltage protection

Note: 1. Guaranteed by design.
2. Only for version with Inhibit function.
3. Dropout voltage is defined as the input-to-output differential when the output voltage drops to 99% of its
nominal value with VOUT +1V applied to VIN.
4. Reference voltage is measured between output and GND pin, with ADJ PIN tied to VOUT
