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
OUT
packages
■ Internal current and thermal limit
■ Only 2.2 µF for stability

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
