Very low drop voltage regulators with inhibit

Features

■ 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

TO-220FP

TO-220

■ Output voltages of 1.5; 1.8; 2.5; 3.3; 4.7; 5; 6;

8; 8.5; 9; 12V

■ Automotive Grade product: 1.8V, 2.5V, 3.3V,

5.0V, 8.0V, 8.5V V

in DPAK and PPAK

packages

■ Internal current and thermal limit

■ Only 2.2 µF for stability

PPAK

DPAK

PENTAWATT

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

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. 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 Table 32 (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.

25°C

■ Supply voltage rejection: 80db (typ.)

■ Temperature range: -40 to 125 °C

Description

The LFxxAB/LFxxC 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 (0.45 V) 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

Table 1.
