The L4931 is a low-dropout voltage regulator available in various packages (SO-8, DPAK, PPAK, and TO-92) with a wide range of output voltages (3.3 V, 3.5 V, 5 V, and 12 V).
Key features include:
Low Power Consumption
Very low quiescent current (typ. 50 μA in OFF mode, 600 μA in ON mode) and low dropout voltage (0.4 V).
Shutdown Functionality
TTL compatible shutdown logic control function available in PPAK and SO-8 packages, allowing for partial shutdown of the board to reduce power consumption.
Stability and Protection
Requires only a 2.2 μF capacitor for stability and features internal current and thermal limit protection.
Automotive-Grade Option
Available as an automotive-grade product in SO-8 package only, qualified according to AEC-Q100 specification.
