LK115XX33 - LK115XX50

Very low drop with inhibit voltage regulators

Features

■ Very low dropout voltage (0.2 V typ.)

■ Very low quiescent current

(Typ. 0.01 µA in off mode, 280 µA in on mode)

■ Output current up to 100 mA

■ Two logic-controlled electronic shutdowns

■ Output voltages of 3.0; 3.3; 5.0 V

■ Internal current and thermal limit

■ Only 2.2 µF for stability

SO-8

■ V

tolerance 3 % at 25 °C

OUT

■ Supply voltage rejection: 80 dB (typ)

■ Temperature range: -40 °C to 125 °C

It requires only a 2.2 µF capacitor for stability

allowing space and cost saving.

Description

The LK115XX series are very low drop regulators

available in SO-8 package and in a wide range of

output voltages.

The very low drop voltage (0.2 V) and the very low

quiescent current (0.01 µA in OFF MODE, 280 µA

in ON MODE) make them particularly suitable for

low noise, low power applications and specially in

battery powered systems.

Both active HIGH and active LOW shutdown logic

control are available (pin 2 and 3). This means

that when the device is used as a local regulator,

it is possible to put a part of the board in standby,

decreasing the total power consumption.
