LDK320

200 mA low quiescent current and high PSRR voltage regulator

Datasheet - preliminary data

Applications



DSC

BD, DVD

Industrial

SOT-89

SOT23-5L

Description

The LDK320 is a low drop voltage regulator,

which provides a maximum output current of

200 mA from an input voltage in the range of

2.5 V to 18 V, with a typical dropout voltage of

100 mV.

Features



Input voltage from 2.5 to 18 V

Very low-dropout voltage (100 mV typ. @

100 mA load)



Low quiescent current (typ. 60 μA, 1 μA in

off mode)

It is stabilized with a ceramic capacitor on the

output.



High PSRR: 88 dB@120 Hz

Low noise

The very good dynamic characteristic, combined

with low drop voltage and low quiescent current

make it suitable for low power battery-powered

applications.

Output voltage tolerance: ± 2.0% @ 25 °C;

(±0.5% version available on request)

Output current up to 200 mA

Wide range of output voltages available on

request: fixed from 1.2 V to 12 V with

100 mV step and adjustable

Logic-controlled electronic shutdown

Compatible with ceramic capacitor

C_OUT= 1 μF



The enable logic control function allows the

LDK320 to be in shutdown mode by consuming a

total current lower than 1 μA.



This device also includes a short-circuit current

limiting, thermal and SOA protections.



Current, SOA and thermal protections

Available in SOT23-5L and SOT-89

packages



Temperature range: -40 °C to 125 °C
