L4931CDT33 Description

Short technical summary and product information.

The STMicroelectronics L4931CDT33 is a linear voltage regulator IC designed for power management applications. It offers a stable, fixed output voltage of 3.3V and can supply a maximum current of 250mA. The device accepts an input voltage up to 20V and features protection against over current and over temperature conditions.

 

With a low dropout voltage of 0.8V at 250mA, the L4931CDT33 is suitable for applications where efficient voltage regulation is required. It operates within a temperature range of -40°C to 125°C.

 

The regulator is housed in a DPAK (TO-252-3) surface mount package, facilitating integration into compact electronic designs. Its PSRR characteristics range from 73dB to 55dB across the 120Hz to 10kHz frequency range, indicating good noise rejection capabilities.
