Categories: Linear, Low Drop Out (LDO) Regulators
Quality Control: Learn More
The STMicroelectronics LD39300PT18-R is a positive fixed output linear voltage regulator designed for high-current applications. This device delivers a stable 1.8V output with a maximum output current of 3A. Featuring a low dropout voltage of 0.4V at 3A, it is suitable for power-sensitive designs. The internal quiescent current is 5 µA, and the supply current does not exceed 2.5 mA. Protection features include over-current and over-temperature shutdown. The LD39300PT18-R offers excellent power supply rejection ratio (PSRR) performance, ranging from 65dB to 55dB across the 120Hz to 1kHz frequency range. It is supplied in a PPAK (TO-252-5, DPAK) surface-mount package and operates within a temperature range of -40°C to 125°C. This component is utilized in industries such as automotive, industrial, and consumer electronics.
