Quality Control: Learn More
STMicroelectronics LD49300PT08R is a positive adjustable linear voltage regulator designed for applications requiring high current density. This device offers a low dropout voltage of 0.4V at a 3A output current, facilitating efficient power delivery. It features an output current capability of up to 3A and an adjustable output voltage range from 0.8V to 4.5V, with a maximum input voltage of 5.5V. The regulator includes over-current and over-temperature protection features for enhanced reliability. With a quiescent current of 4mA and a supply current of 6mA (max), it is suitable for power-sensitive designs. The PPAK package (TO-252-5) supports surface mounting. The LD49300PT08R is utilized in automotive, industrial, and consumer electronics sectors. It provides excellent power supply rejection ratio (PSRR) of 68dB at 120Hz.
