LDK220

200 mA low quiescent current and low noise LDO

Datasheet - production data

Applications



Battery-powered equipment

Set-top box

PC and laptop

Industrial

Description

The LDK220 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 13.2 V, with a typical dropout voltage of

100 mV.

A ceramic capacitor stabilizes it on the output.

Features

The very low drop voltage, low quiescent current

and low noise make it suitable for battery-

powered applications.



Input voltage from 2.5 to 13.2 V

Very low-dropout voltage (100 mV typ. @

100 mA load)

The enable logic control function puts the

LDK220 in shutdown mode allowing a total

current consumption lower than 1 µA.



Low quiescent current (typ. 55 µA, 1 µA in

off mode)

Low noise

Output voltage tolerance: ± 2.0% @ 25 °C

200 mA guaranteed output current

Wide range of output voltages available on

request: fixed from 1.2 V to 12 V with

100 mV step and adjustable



The device also includes a short-circuit constant

current limiting and thermal protection.



Logic-controlled electronic shutdown

Compatible with ceramic capacitor

C_OUT= 1 µF



Internal current and thermal limit

Available in SOT23-5L, SOT323-5L, SOT-89

and DFN6-1.2x1.3 packages

Temperature range: -40 °C to 125 °C
