LP2951A
LP2951A is 150mA ADJUSTABLE VOLTAGE REGULATOR manufactured by SEMTECH.
DESCRIPTION
The LP2951A is an improved version of the LP2951 and Features tighter tolerance on the output voltage and reference voltage specifications. Both the LP2951 and LP2951A feature 150m A output current capability. The LP2951 series of low power voltage regulators have low quiescent current and low dropout voltage. The quiescent current increases minimally during dropout conditions thereby extending battery life. Available in the eight lead SOIC package, the LP2951 series includes Features such as shutdown and low output voltage detect (typically due to low battery conditions) . This function may also be used as a power on reset function when triggered by CMOS or TTL inputs. The circuit can be used as a fixed voltage 5 volt regulator or adjusted between 1.24 volts and 29 volts using external resistor pairs.
