This file is about L4931ABxx L4931Cxx series. L4931ABxx L4931Cxx series are low voltage drop regulators with inhibit function. It has extremely low drop voltage (0.4V), extremely low quiescent current (typical 50μA in off mode, 600μA in on mode), output current up to 250mA, logic-controlled electronic shutdown, output voltage of 2.7;3.3;3.5;5;8;12V, automotive grade product: 2.7V, 3.3V, 3.5V VOUT only in SO-8 package, internal current and thermal limit, only 2.2µF for stability, available in ±1% (AB) or 2% (C) selection at 25°C, supply voltage rejection: 70dB typical for 5V version, temperature range: -40 to 125°C.
The L4931ABxx and L4931Cxx are very low dropout voltage regulators available in TO-220, SO-8, DPAK, PPAK, and TO-92 packages. They feature a very low dropout voltage of 0.4 V and very low quiescent current, making them suitable for low noise, low power, and battery-powered applications. The devices offer output voltages ranging from 2.7 V to 12 V and include an internal current and thermal limit for protection.
