LD39015Jxx
150 mA low quiescent current
low noise voltage regulator
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)
■ Low noise (54 µV
from 10 Hz to 100 kHz at
Flip-chip 4
RMS
V
= 1.8 V)
OUT
■ Output voltage tolerance: 2.0% @ 25 °C
■ 150 mA guaranteed output current
74 dB at low frequencies and starts to roll off at 10
kHz. Enable logic control function puts the
LD39015Jxx 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
■ Wide range of output voltages available on
request: 0.8 V to 4.5 V with 100 mV step
■ Logic-controlled electronic shutdown
■ Compatible with ceramic capacitor
applications are mobile phones, personal digital
assistant (PDAs), cordless phone and similar
battery powered systems.

■ Flip-chip 4 bumps 1.1 x 1.1 mm.
■ Temperature range: -40 °C to 125 °C
Description
The LD39015Jxx provides 150 mA maximum
current from an input voltage ranging from 1.5 V
to 5.5 V with a typical dropout voltage of 80 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

1. Dropout voltage is the input-to-output voltage difference at which the output voltage is 100 mV below its nominal value. This
specification does not apply for output voltages below 1.5 V.
2. Turn-on time is time measured between the enable input just exceeding VEN High Value and the output voltage just
reaching 95% of its nominal value.
