The STMicroelectronics L4931CPT33 is a positive fixed output linear voltage regulator IC, delivering a stable 3.3V at up to 250mA. This device features excellent power supply rejection ratio (PSRR) performance, ranging from 73dB at 120Hz to 55dB at 10kHz, making it suitable for applications sensitive to power supply noise. The L4931CPT33 offers over-current and over-temperature protection for robust operation. With a maximum input voltage of 20V and a dropout voltage of 0.8V at 250mA, it is designed for efficiency in power-sensitive designs. The quiescent current is a low 1mA, with a maximum supply current of 6mA. This component is housed in a TO-252-5, DPAK (5 leads + tab) surface-mount package, often referred to as PPAK, and operates across a temperature range of -40°C to 125°C. It finds application in automotive, industrial, and consumer electronics where reliable voltage regulation is critical.
