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.
