Description
SOT323-5L
enable logic control function puts the LD59015xx
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.
The LD59015xx provides 150 mA of maximum
current from an input voltage ranging from 2.3 V
to 5.5 V, with 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 frequencies and starts to roll off at 10 kHz. An
