L4931
Very low drop voltage regulators with inhibit
Datasheet - production data
Description
The L4931 is a very low drop regulator available
in 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 it particularly suitable
for low noise, low power applications and
especially in battery-powered systems.
A TTL compatible shutdown logic control function
is available in PPAK and SO-8 packages. This
means that when the device is used as a local
regulator, a part of the board can be put in
standby mode, decreasing the total power
consumption. It requires only a 2.2 µF capacitor
for stability allowing space and cost saving.

Logic controlled electronic shutdown
Output voltages: 3.3; 3.5; 5; 12 V
Automotive-grade product: 3.3 V VOUT in
SO-8 package only
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: 70 dB typ. for 5 V
version
Temperature range: from -40 to 125 °C
August 2017
The L4931 is available as automotive-grade in
SO-8 package only. This device is qualified
according to the specification AEC-Q100 of the
automotive market, in the temperature range
from 40 °C to 125 °C, and the statistical tests:
PAT, SYL, SBL are performed.
