LD39020

200 mA very low quiescent current linear regulator IC

Datasheet - production data

Applications



Mobile phones

Personal digital assistants (PDAs)

Digital still cameras (DSC)

Cordless phones and similar battery-

powered systems

SOT23-5L

DFN1x1-4L



Portable media players

Description

The LD39020 high accuracy voltage regulator

provides 200 mA of maximum current from an

input voltage ranging from 1.5 V to 5.5 V, with a

typical dropout voltage of 200 mV.

Features



Input voltage from 1.5 to 5.5 V

Ultra low dropout voltage (200 mV typ. at

200 mA load)

It is available in DFN 1x1-4L and SOT23-5L

packages, allowing the maximum space saving.



Very low quiescent current (20 µA typ at no

load, 0.03 µA typ in off mode)

Output voltage tolerance: ±0.5% (A version)

or ± 2.0% @ 25 °C (standard version)

200 mA guaranteed output current

High PSRR (80 dB@1 kHz, 50 db@100

kHz)

Wide range of output voltages available on

request: from 0.8 V up to 5.0 V in 50 mV

step

The device is stabilized with a ceramic capacitor

on the output. The ultra low drop voltage, low

quiescent current and low noise features,

together with the internal soft-start circuit, make

the LD39020 suitable for low power battery-

operated applications.



An enable logic control function puts the

LD39020 in shutdown mode allowing a total

current consumption lower than 0.1 µA. Constant

current and thermal protection are provided.



Logic-controlled electronic shutdown

Internal soft-start

Optional output voltage discharge feature

Compatible with ceramic capacitor C_OUT

0.47 µF



Internal constant current and thermal

protections



Available in DFN 1x1-4L and SOT23-5L

Operating temperature range: -40 °C to

125 °C
