LD39015J

150 mA low quiescent current low noise voltage regulator

Datasheet

Features

• Input voltage from 1.5 to 5.5 V

• Ultra low dropout voltage (90 mV typ. at 100

mA load)

• Very low quiescent current (20 µA typ. at no

load, 35 µA typ. at 150 mA load, 1 µA max in off

mode)

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

• 150 mA guaranteed output current

• Wide range of output voltages available on

request: 0.8 V to 4.5 V with 100 mV step

• Logic-controlled electronic shutdown

• Internal current and thermal limit

• Flip-chip 4 bumps 1.1 x 1.1 mm.

• Temperature range: -40 °C to 125 °C

Description

The LD39015J provides 150 mA maximum

current from an input voltage ranging from 1.5 V

to 5.5 V with a typical dropout voltage of 90 mV. It

is stable with ceramic capacitor. 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

74 dB at low frequencies and starts to roll off at 10

kHz. Enable logic control function puts the

LD39015J in shut-down mode allowing a total

current consumption lower than 1 µA. The device

also includes a short-circuit constant current

limiting and thermal protection. Typical

applications are mobile phones, personal digital

assistant (PDAs), cordless phone and similar

battery powered systems.
