Very low drop voltage regulators with inhibit

Datasheet

- production data

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 2.5; 3.3; 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 KF series are very low drop regulators

available in SO-8 and DPAK packages and in a

wide range of output voltages.

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

low quiescent current make them particularly

suitable for low noise, low power applications and

especially 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.
