LF00 series

Very low drop voltage regulators with inhibit

Feature summary

■ Very low dropout voltage (0.45V)

■ 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; 1.8; 2.5; 2.7; 3; 3.3; 3.5;

4; 5; 6; 8; 8.5; 9; 12V

■ Internal current and thermal limit

■ Only 2.2 µF for stability

■ Available in ± 1% (AB) or ± 2% (C) selection at

25°C

■ Supply voltage rejection: 80db (typ.)

■ Temperature range: -40 to 125°C

Description

The LF00 series are very Low Drop regulators

available in PENTAWATT, TO-220, TO-220FP,

DPAK and PPAK package and in a wide range of

output voltages.

The very Low Drop voltage (0.45V) and the very

low quiescent current make them particularly

suitable for Low Noise, Low Power applications

and specially in battery powered systems.

In the 5 pins configuration (PENTAWATT and

PPAK) a Shutdown Logic Control function is

available (pin 2, 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. In the

three terminal configuration the device has the

same electrical performance, but is fixed in the

ON state. It requires only a 2.2 µF capacitor for

stability allowing space and cost saving.
