L4931CD33 Description

Short technical summary and product information.

The STMicroelectronics L4931CD33TR is a linear voltage regulator designed for power management applications. It provides a stable, fixed output voltage of 3.3V and can deliver a continuous output current of up to 250mA.

 

Key electrical characteristics include a maximum input voltage of 20V and a low dropout voltage of 0.8V when operating at the full 250mA output current. The quiescent current is typically 1mA, with a maximum supply current of 6mA. The device also offers a Power Supply Rejection Ratio (PSRR) ranging from 73dB to 55dB.

 

This component is housed in an 8-SOIC package and is suitable for surface mount applications. It is supplied in Cut Tape (CT) and Digi-Reel® packaging formats.

 

The L4931CD33TR is part of the Voltage Regulators - Linear, Low Drop Out (LDO) Regulators category within Power Management ICs.
