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.
