74 dB at low frequencies and starts to roll off at 10
kHz. Enable logic control function puts the
LD39015Jxx in shut-down mode allowing a total
current consumption lower than 1 µA. The device
also includes a short-circuit constant current
limiting and thermal protection. Typical
applications are mobile phones, personal digital
assistant (PDAs), cordless phone and similar
battery powered systems.
Description
The LD39015Jxx provides 150 mA maximum
current from an input voltage ranging from 1.5 V
to 5.5 V with a typical dropout voltage of 80 mV. It
is stable with ceramic capacitor. The ultra low
drop-voltage, low quiescent current and low noise
features make it suitable for low power battery
powered applications. Power supply rejection is

1. 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 1.5 V.
2. Turn-on time is time measured between the enable input just exceeding VEN High Value and the output voltage just
reaching 95% of its nominal value.
