LD39115Jxx

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 (20 µA typ. at no

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

mode)

■ Very low noise (33 µV

from 1 kHz to 100

RMS

Flip-chip 4

kHz at V

= 1.8 V)

OUT

■ Output voltage tolerance: 2.0 % @ 25 °C

■ 150 mA guaranteed output current

■ Wide range of output voltages available on

Description

request: 0.8 V to 4.5 V with 100 mV step

The LD39115Jxx 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 stabilized with a 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. An enable logic control function

puts the LD39115Jxx in shutdown mode allowing

a total current consumption lower than 1 µA. The

device also includes a short-circuit constant

current limiting and thermal protection.

■ Logic-controlled electronic shutdown

■ Compatible with ceramic capacitor C

■ Internal current and thermal limit

= 1 µF

OUT

■ Flip-chip 4 bumps 0.8 x 0.8 mm. pitch

■ Temperature range: -40 °C to 125 °C

Applications

■ Mobile phones

■ Personal digital assistants (PDAs)

■ Cordless phones and similar battery-powered

systems
