STMicroelectronics LF33ABDT is a positive fixed output linear voltage regulator IC. This device offers a stable 3.3V output with a maximum current capability of 500mA. Designed for surface mount applications, it is supplied in a DPAK (TO-252-3) package. The LF33ABDT features over-current and over-temperature protection, along with a high power supply rejection ratio (PSRR) ranging from 80dB to 65dB across a frequency range of 120Hz to 65dB. With a maximum input voltage of 16V and an output voltage dropout of 0.7V at 500mA, this regulator is suitable for use in automotive, industrial, and consumer electronics. The operating temperature range is -40°C to 125°C, and it is available in tube packaging.
