L4931Cxx
Very low drop voltage regulators with inhibit
Features
■ Very low dropout voltage (0.4 V)
■ Very low quiescent current
■ (Typ. 50 µA in off mode, 600 µA in on mode)
■ Output current up to 250 mA
■ Logic-controlled electronic shutdown
■ Output voltages of 2.7; 3.3; 3.5; 5; 8; 12 V
■ Automotive Grade product: 2.7 V, 3.3 V, 3.5 V
TO-92
TO-220
V
only in SO-8 package
OUT
■ Internal current and thermal limit
■ Only 2.2 µF for stability
PPAK
SO-8
DPAK
■ Available in 1 ꢀ (Aꢁ) or 2 ꢀ (C) selection at
25 °C
■ Supply voltage rejection: 70 dꢁ typ. for 5 V
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.
version
■ Temperature range: -40 to 125 °C
Description
The L4931 is available as Automotive Grade in
SO-8 package only, for the options of output
voltages whose commercial Part Numbers are
shown in the Table 19 on page 34 (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, SꢁL are
performed.
The L4931Aꢁxx L4931Cxx are very Low Drop
regulators available in TO-220, SO-8, DPAK,
PPAK and TO-92 packages and in a wide range of
output voltages.
The very low drop voltage (0.4 V) and the very low
quiescent current make them particularly suitable
for low noise, low power applications and
specially in battery powered systems.
A TTL compatible shutdown logic control function
is available in PPAK and SO-8 packages.
