Description

The LD59015xx provides 150 mA of maximum

current from an input voltage ranging from 2.3 V

to 5.5 V, with a typical dropout voltage of 150 mV.

It is stable with ceramic capacitors. High PSRR,

low quiescent current and low noise features

make it suitable for low power battery-powered

applications. Power supply rejection is 80 dB at

low frequencies and starts to roll off at 10 kHz. An

enable logic control function puts the LD59015xx

in shutdown mode, allowing a total current

consumption lower than 1 µA. The device also

includes short-circuit constant current limiting and

thermal protection. Typical applications are

mobile phones, personal digital assistants

(PDAs), cordless phones and similar battery-

powered systems.
