LD1117DT33TR Description

Short technical summary and product information.

The STMicroelectronics LD1117DT33TR is a fixed output linear voltage regulator designed for various power management applications. It delivers a stable 3.3V output voltage with a maximum current capability of 800mA. The device operates within a temperature range of 0°C to 125°C and offers protection features such as over current and over temperature.

 

This regulator is housed in a DPAK (TO-252-3) surface mount package, making it suitable for space-constrained designs. Its PSRR of 75dB at 120Hz indicates good noise rejection. The LD1117DT33TR is a reliable choice for applications requiring a consistent and regulated power supply.

 

Key electrical characteristics include a voltage dropout of 1.2V at 800mA and a positive output configuration. The component is designed for ease of integration into printed circuit boards via surface mounting.
