LDCL015
150 mA capless ultra low drop linear regulator ICs
Datasheet
-
production data
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
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.
