Overview
L4931 Very low drop voltage regulators with inhibit 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: 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 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 PP...
