Texas Instruments LP38691DTX-2-5 is a high-performance, low-dropout (LDO) linear voltage regulator designed for demanding applications. This positive fixed output regulator provides a stable 2.5V with an output current capability of 500mA. Featuring a low quiescent current of 55 µA and a supply current of 100 µA (max), it contributes to power efficiency in battery-operated devices. The device boasts a low dropout voltage of 0.73V at 500mA, enabling operation from lower input voltages. Protection features include over-temperature shutdown. With a power supply rejection ratio (PSRR) of 55dB at 120Hz, it effectively filters noise for sensitive circuitry. The LP38691DTX-2-5 is housed in a TO-252-3 (DPAK) surface-mount package, suitable for high-volume manufacturing. Typical applications include automotive electronics, consumer electronics, and industrial systems requiring reliable voltage regulation.
