Texas Instruments LP38851SX-ADJ is an adjustable positive linear voltage regulator designed for high-performance applications. This device delivers up to 800mA output current with a low dropout voltage of 0.2V at 800mA, ensuring efficient power regulation. The output voltage is adjustable from 0.8V to a maximum of 1.8V. Key control features include an enable pin and a soft-start function for controlled power-up sequences.
Protection mechanisms such as over current, over temperature, short circuit, and under voltage lockout (UVLO) are integrated for robust operation. The device exhibits excellent power supply rejection ratio (PSRR) performance, ranging from 72dB to 61dB across the 120Hz to 1kHz frequency range. Supplied in a TO-263-8, D2PAK package, suitable for surface mounting, the LP38851SX-ADJ operates within an ambient temperature range of -40°C to 125°C. This component finds application in automotive, industrial, and communication systems requiring stable and low-noise power delivery.
