LD39030DTPU33R Description

Short technical summary and product information.

The STMicroelectronics LD39030DTPU33R is a linear voltage regulator IC with a fixed output voltage of 3.3V and an output current capability of 300mA. It features a very low quiescent current of 130 µA, making it suitable for power-sensitive applications.

 

The regulator operates with an input voltage range from 1.5V to 5.5V. It offers a high PSRR of 80 dB at 1kHz, helping to filter out noise from the power supply. The device has a dropout voltage of 330mV at 300mA.

 

Packaged in a compact 4-DFN (1x1) surface-mount case, the LD39030DTPU33R is designed for space-constrained designs. It operates within a temperature range of -40°C to +125°C. Protection features include over current and over temperature.

 

This LDO regulator is part of the ld39030 series and is supplied on a reel.
