LF33ABDT Description

Short technical summary and product information.

The STMicroelectronics LF33ABDT is a low dropout (LDO) linear voltage regulator designed for efficient power management. It provides a stable 3.3V output voltage with a maximum output current of 500mA. The device features a low dropout voltage of 0.7V at 500mA, making it suitable for battery-powered applications where voltage efficiency is critical.

 

With an input voltage range up to 16V and an operating temperature range of -40°C to 125°C, the LF33ABDT offers robust performance in various environmental conditions. It includes over-current and over-temperature protection features for enhanced reliability. The regulator is housed in a surface-mount DPAK package (TO-252-3), facilitating integration into compact electronic designs.

 

This LDO regulator is ideal for applications requiring a fixed, regulated voltage supply. Its low quiescent current and high PSRR (80dB typical) contribute to low noise and stable operation, particularly in sensitive electronic circuits. The fixed output type and positive output configuration simplify circuit design.
