150 mA low quiescent current
low noise voltage regulator
Features
■ Input voltage from 1.5 to 5.5 V
■ Ultra low dropout voltage (80 mV typ. at 100
mA load)
■ Very low quiescent current (18 µA typ. at no
load, 35 µA typ. at 150 mA load, 1 µA max in off
mode)
■ Very low noise without bypass capacitor
(29 µV
at V
= 0.8 V)
SOT666
SOT23-5L
RMS
OUT
■ Output voltage tolerance: 2.0% @ 25 °C
■ 150 mA guaranteed output current
■ Wide range of output voltages available on
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 65 dB at low frequencies and starts to
roll off at 10 kHz. Enable logic control function
puts the LD39015XX in shut-down mode allowing
a total current consumption lower than 1 µA. The
device also includes short-circuit constant current
limiting and thermal protection. Typical
request: 0.8 V to 3.3 V with 100 mV step
■ Logic-controlled electronic shutdown
■ Compatible with ceramic capacitors
C
= 1 µF
OUT
■ Internal current and thermal limit
■ Available in SOT666 and SOT23-5L packages
■ Temperature range: -40 °C to 125 °C
applications are mobile phones, personal digital
assistants (PDAs), cordless phones or similar
battery-powered systems.
Description
The LD39015XX series provides 150 mA

1. For VOUT(NOM) < 1.2 V, VIN = 1.5 V
2. All transient values are guaranteed by design, not production tested
3. 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
4. Turn-on time is the time measured between the enable input just exceeding VEN High Value and the output voltage just
reaching 95 % of its nominal value
