Categories: Linear, Low Drop Out (LDO) Regulators
Quality Control: Learn More
The STMicroelectronics L4931CPT33-TR is a positive fixed voltage linear regulator IC. This component provides a stable 3.3V output with a maximum output current of 250mA. It features a low dropout voltage of 0.8V at 250mA, making it suitable for applications where voltage headroom is critical. The device includes over-current and over-temperature protection for enhanced reliability. With a quiescent current of 1mA and a maximum input voltage of 20V, it is designed for efficient operation. The regulator exhibits a Power Supply Rejection Ratio (PSRR) ranging from 73dB at 120Hz to 55dB at 10kHz. This component is supplied in a PPAK (TO-252-5, DPAK) surface-mount package, presented on tape and reel. It finds application in automotive, industrial, and consumer electronics sectors.
