LD59015
150 mA low noise high PSRR linear voltage regulator
Datasheet
-
production data
Description
The LD59015 provides 150 mA maximum current
with an input voltage range from 2.4 V to 5.5 V,
and a typical dropout voltage of 150 mV. It is
stable with ceramic capacitors. High PSRR, low
quiescent current and low noise features make it
suitable for low power battery-powered
applications. Power supply rejection is 80 dB at
low frequency and starts to roll off at 10 kHz. The
enable logic control function puts the LD59015 in
shutdown mode, allowing a total current
consumption lower than 1 µA. The device also
includes short-circuit constant current limiting and
thermal protection. Typical applications are
mobile phones, personal digital assistants
(PDAs), cordless phones and similar battery-
powered systems.
