DESCRIPTION

The UTC LR1142 is a CMOS-based 500mA voltage regulator
with low supply current, low dropout, adjustable output voltage, The
device offering high PSRR and low dropout. The quiescent current
is as low as 35μA, further prolonging the battery life. The UTC
LR1142 also works with low-ESR ceramic capacitors, reducing the
amount of board space necessary for power applications, critical in
handheld wireless devices.
The UTC LR1142 consumes typical 0.7μA in shutdown mode.
The other features include low dropout voltage, high output
accuracy, current limit protection, and enable/shutdown control.
