10 kHz. The Enable logic control function puts the
LDCL015 in shutdown mode, reducing the total
current consumption to less than 1 µA. The
device also includes short-circuit constant current
limit and thermal protection. Typical applications
are mobile phones, personal digital assistants
and similar battery-powered systems.
Description
The LDCL015 provides 150 mA of maximum
current from an input voltage ranging from 1.8 V
to 5.5 V, with a typical dropout voltage of 50 mV. It
is stable with no input or output capacitor. Low
quiescent current, low noise and capless
operation make it suitable for low power battery-
powered applications and allows the reduction of
board size. Typical power supply rejection ratio is
52 dB at low frequencies, and starts to roll off at
