Quality Control: Learn More
The STMicroelectronics L4931CDT33 is a positive fixed output linear voltage regulator. This component provides a stable 3.3V output with a maximum current capability of 250mA. Designed for surface mount applications, it is supplied in a DPAK (TO-252-3) package. Key features include a maximum input voltage of 20V and a typical dropout voltage of 0.8V at 250mA. Protection features such as over-current and over-temperature shutdown are integrated. The device exhibits a Power Supply Rejection Ratio (PSRR) ranging from 73dB to 55dB across the 120Hz to 10kHz frequency range. It operates within an ambient temperature range of -40°C to 125°C. Applications for this regulator include automotive systems and industrial control equipment.
