Texas Instruments LP38691DTX-3-3 is a fixed 3.3V positive linear voltage regulator designed for demanding applications. This LDO regulator delivers a stable 500mA output current from an input voltage up to 10V. Featuring a low quiescent current of 55µA and a maximum supply current of 100µA, it is well-suited for power-sensitive designs. The device offers a low voltage dropout of 0.55V at its full 500mA output, ensuring efficient operation even under significant load. Protection features include over-temperature shutdown. With a PSRR of 55dB at 120Hz, it provides excellent noise immunity. The LP38691DTX-3-3 is supplied in a TO-252-3 (DPAK) surface-mount package and operates across a wide temperature range of -40°C to 125°C. This component is commonly utilized in automotive, industrial, and consumer electronics power management systems.
