150 mA low quiescent current and low noise voltage regulator
Datasheet - production data
SOT666
SOT23-5L
• 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
Features
current with an input voltage range from 1.5 V to
5.5 V and a typical dropout voltage of 80 mV. It is
• Input voltage from 1.5 to 5.5 V
stable with ceramic capacitors. The ultra low drop
• 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)
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
• Very low noise without bypass capacitor
current consumption lower than 1 µA. The device
(29 µVRMS at VOUT = 0.8 V)
• Output voltage tolerance: ± 2.0% @ 25 °C
• 150 mA guaranteed output current
also includes short-circuit constant current limiting
and thermal protection. Typical applications are
mobile phones, personal digital assistants
(PDAs), cordless phones or similar battery-
• Wide range of output voltages available on
powered systems.
