Description
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 µVRMS from 10 Hz to 100 kHz at
VOUT = 1.8 V)
• Output voltage tolerance: ± 2.0% @ 25 °C
• 150 mA guaranteed output current
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.
• Wide range of output voltages available on
request: 0.8 V to 4.5 V with 100 mV step
