L4931CDT33-TR Description

Short technical summary and product information.

The STMicroelectronics L4931CDT33-TR is a linear voltage regulator designed for efficient power management. It provides a stable, fixed output voltage of 3.3V and can deliver up to 250mA of current. The regulator operates with a maximum input voltage of 20V and features a low dropout voltage of 0.8V at 250mA.

 

Key electrical characteristics include a quiescent current of 1mA and a supply current of up to 6mA. Protection features such as over-current and over-temperature protection are integrated for enhanced reliability. The device also offers good power supply rejection ratio (PSRR) ranging from 73dB to 55dB across a frequency range of 120Hz to 10kHz.

 

This component is housed in a TO-252-3, DPak (2 Leads + Tab), SC-63 package, suitable for surface mount applications. The operating temperature range is -40°C to 125°C, making it suitable for various environmental conditions. The RoHS status is reported as RoHS3 Compliant.
