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. 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 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.
