Datasheet - production data
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: 2.7; 3.3; 3.5; 5; 8; 12 V Automotive-grade product: 2.7 V, 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 Supply voltage rejection: 70 dB typ. for 5 V
version Temperature range: from -40 to 125 °C
DescriptionThe 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.
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 °C to 125 °C, and the statistical tests: PAT,
SYL, SBL are performed.
