IC REG LINEAR 1.2V 3A PPAKManufacturer: STMicroelectronics
Categories: Linear, Low Drop Out (LDO) Regulators
Quality Control: Learn More
The STMicroelectronics LD49300PT12R is a positive fixed output linear voltage regulator IC. This component delivers a stable 1.2V output with a maximum output current of 3A. Designed for surface mounting, it utilizes a PPAK (TO-252-5, DPAK) package, offering a compact solution for space-constrained applications. Key features include an enable control pin for power management and robust protection circuitry against over current and over temperature conditions. With a quiescent current of 4 mA and a maximum input voltage of 5.5V, the LD49300PT12R exhibits a low dropout voltage of 0.4V at 3A. Its excellent power supply rejection ratio (PSRR) of 68 dB at 120 Hz makes it suitable for noise-sensitive applications in sectors such as automotive and industrial automation. The device operates within a temperature range of -25°C to 125°C and is supplied in cut tape packaging.
