The STMicroelectronics L4931CD50 is a positive fixed linear voltage regulator designed for applications demanding stable 5V output. This component delivers a regulated 250mA output current with a maximum input voltage of 20V. Featuring a low dropout voltage of 0.8V at full load, it ensures efficient operation even with minimal voltage headroom. The regulator incorporates over-current and over-temperature protection for enhanced reliability. Its 8-SOIC package is suitable for surface mount assembly. The L4931CD50 is commonly found in automotive, industrial, and consumer electronics power management systems. The quiescent current is rated at 1mA, with a maximum supply current of 6mA. The device offers excellent power supply rejection ratio (PSRR) ranging from 70dB to 55dB across a frequency range of 120Hz to 10kHz, making it effective in filtering noise from the input supply. It operates within a temperature range of -40°C to 125°C.
