request: 0.8 V to 3.3 V in 100 mV steps

• Logic-controlled electronic shutdown

• Compatible with ceramic capacitors

• Very high PSRR (80 dB @ 100 Hz, 76 @

10 kHz, 54 @ 100 kHz)

• Internal current and thermal limit

• Package: SOT323-5L

• Temperature range: -40 °C to 125 °C

Description

The LD59015 provides 150 mA maximum current

with an input voltage range from 2.4 V to 5.5 V,

and 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 frequency and starts to roll off at 10 kHz. The

enable logic control function puts the LD59015 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.
