LFXX

Very low drop voltage regulator with inhibit function

Datasheet - production data

Description

The LFXX is a very low drop regulator available

in TO-220, TO-220FP, DPAK and PPAK

packages and in a wide range of output voltages.

The low drop voltage (0.45 V) and low quiescent

current make it particularly suitable for low-noise,

low-power applications and especially in battery-

powered systems. In the 5 pin configuration

(PPAK) a shutdown logic control function is

available (pin 2, TTL compatible). This means

that when the device is used as a local regulator,

a part of the board can be put in standby,

decreasing the total power consumption. In the

three terminal configuration, the device has the

same electrical performance, but it is fixed in ON

state. It requires a capacitor of only 2.2 µF for

stability, saving board space and costs. The

LFXX is available as automotive grade in DPAK

and PPAK packages, for the options of output

voltages whose commercial part numbers are

shown in the order codes. These devices are

qualified according to the specification

AEC-Q100 of the automotive market, in the

temperature range -40 °C to 125 °C, and the

statistical tests PAT, SYL, SBL are performed.

Features



Very low-dropout voltage (0.45 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; 1.8; 2.5; 3.3; 4.7; 5;

6; 8; 8.5; 9; 12 V

Automotive grade product: 1.8 V, 2.5 V,

3.3 V, 5.0 V, 8.0 V, 8.5 V V

OUT

in DPAK and

PPAK packages

Internal current and thermal limit

Only 2.2 µF for stability

Available in ±1% (AB), ±1.5% (AC) or

±2% (C) selection at 25 °C

Supply voltage rejection: 80 db (typ.)

Temperature range: from -40 to 125 °C
