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 150mA 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 con-
ditions) . 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 regula-
tor or adjusted between 1.24 volts and 29 volts using
external resistor pairs.
FEATURES
= Guaranteed 150mA current
= Adjustable output voltage - 1.24V to 29V
= Accurate 5V output @150mA
= Low dropout voltage - 450mV @ 150mA
= Regulator or reference functions
= Direct replacement for LP2951AC, MIC2951-02,
AS2951AC
APPLICATIONS
= Microcontroller supplies
= Linear regulators
= Adjustable supplies
= Switching power supplies - post-regulation
= Portable modems
= Battery powered systems
= Cellular telephones
= Voltage references
