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

• A 2.2 µF capacitor for stability

• VOUT tolerance ± 3% at 25 °C

• Supply voltage rejection: 80 dB (typ.)

• Temperature range: -40 °C to 125 °C

Description

The LK115 is a series of very low drop voltage

regulators, available in SO-8 package.

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

quiescent current (0.01 µA in OFF mode, 280 µA

in ON mode) make it particularly suitable for low

noise, low power applications and especially 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.

It only requires a 2.2 µF capacitor for stability

saving space and costs.
