LD1117DT33 Description

Short technical summary and product information.

The STMicroelectronics LD1117DT33 is a linear voltage regulator designed for various applications requiring a stable 3.3V power supply. It can deliver a continuous output current of up to 800mA, with a typical voltage dropout of 1.2V at this current. The device operates within a temperature range of 0°C to 125°C.

 

This regulator is housed in a DPAK (TO-252-3) surface mount package, making it suitable for space-constrained designs. It includes over-current and over-temperature protection features for enhanced reliability. The PSRR is rated at 75dB at 120Hz.

 

Key electrical characteristics include a fixed positive output voltage and a single regulator channel. The RoHS status is compliant with RoHS3 standards, and it has an MSL rating of 1.
