STMicroelectronics Voltage Regulators - Linear L4931CD120

The L4931CD120 is a linear voltage regulator from Quarktwin Technology Ltd. designed to provide a fixed output voltage of 12 V with a maximum output current of 250 mA. It features a very low dropout voltage of 0.4 V and operates with a low quiescent current of 600 ¬µA in the ON mode and 50 ¬µA in the OFF mode, making it suitable for low power and battery-operated applications. The device includes a logic-controlled electronic shutdown feature, allowing for reduced power consumption when not in use. Stability is achieved with a minimal capacitance requirement of only 2.2 ¬µF. The L4931CD120 is qualified as an automotive-grade product, adhering to AEC-Q100 specifications, and operates effectively within a temperature range of -40 to 125 ¬8C.
