STMicroelectronics LD49300PT10R is a high-performance linear voltage regulator with a fixed 1V output and a 3A current capability. This positive fixed output regulator is designed for demanding applications requiring stable voltage delivery. Key features include a low dropout voltage of 0.4V at 3A, ensuring efficient operation even under heavy load conditions. The device offers robust protection mechanisms, including over-current and over-temperature shutdown. With an input voltage range up to 5.5V and a quiescent current of 4mA, it is suitable for power-sensitive designs. The regulator provides excellent power supply rejection ratio (PSRR) of 68dB at 120Hz. The LD49300PT10R is supplied in a PPAK (TO-252-5, DPAK) surface-mount package, ideal for efficient thermal management in automotive and industrial sectors. This component is available on Tape & Reel (TR).
