• Ultra low-dropout voltage (80 mV typ. at 100

mA load)

• Very low quiescent current (18 µA typ. at no

load, 38 µA typ. at 150 mA load, 1 µA max. in

OFF mode)

• Very low noise without bypass capacitor

• Output voltage tolerance: ± 2.0% @ 25 °C

• 150 mA guaranteed output current

• Wide range of output voltages available on

request: 0.8 V to 3.3 V with 100 mV step

• Logic-controlled electronic shutdown

• Internal current and thermal limit

• Available in SOT666 and SOT23-5L packages

• Temperature range: -40 °C to 125 °C

Description

The LD39015 series provides 150 mA maximum

current with an input voltage range from 1.5 V to

5.5 V and a typical dropout voltage of 80 mV. It is

stable with ceramic capacitors. The ultra low drop

voltage, low quiescent current and low noise

features make it suitable for low power battery-

powered applications. Power supply rejection is

65 dB at low frequencies and starts rolling off at

10 kHz. Enable logic control function puts the

LD39015 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 or similar battery-

powered systems.
