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 batterypowered systems.
Description
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

1. For VOUT(NOM) < 1.3 V, VIN = 2.3 V.
2. Dropout voltage is the input-to-output voltage difference at which the output voltage is 100 mV below its nominal value. This
specification does not apply for output voltages below 1.7 V.
3. Turn-on time is time measured between the enable input just exceeding the VEN high value and the output voltage just
reaching 95% of its nominal value.
