STMicroelectronics LD49150PT12R is a high-performance fixed 1.2V positive linear voltage regulator with a 1.5A output current capability. This device features a low dropout voltage of 0.2V at maximum output current, enabling efficient power delivery in space-constrained designs. The regulator operates from an input voltage range up to 5.5V and offers excellent power supply rejection ratio (PSRR) of 68dB at 120Hz. Integrated protection features include over-current and over-temperature shutdown, ensuring robust operation. The LD49150PT12R is supplied in a PPAK (TO-252-5, DPAK) package, suitable for surface mounting. Typical applications include automotive systems, consumer electronics, and industrial equipment where reliable voltage regulation is critical. The quiescent current is 4mA, with a maximum supply current of 6mA.
