KFxxB

Very low drop voltage regulators with inhibit

Features

■ Very low dropout voltage (0.4 V)

■ Very low quiescent current (typ. 50 µA in OFF

mode, 500 µA in ON mode)

■ Output current up to 500 mA

■ Logic-controlled electronic shutdown

■ Output voltages of 1.5; 2.5; 3.3; 4; 5; 8 V

■ Internal current and thermal limit

■ Only 2.2 µF for stability

■ Available in ± 2 % accuracy at 25 °C

■ Supply voltage rejection: 70 db (typ.)

■ Temperature range: -40 to 125 °C

Description

The KFxx series are very low drop regulators

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

output voltages.

The very low drop voltage (0.4 V) and the very low

quiescent current make them particularly

suitable for low noise, low power applications and

specially in battery powered systems.

A shutdown logic control function is available (pin

5, TTL compatible). 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 requires only a 2.2 µF

capacitor for stability allowing space and cost

saving.
