نظرة عامة على المنتج
The TLV70233DBVR from Texas Instruments is a 300mA low-dropout (LDO) linear regulator with a fixed 3.3V output in a 5-pin SOT-23 package. Featuring 220mV dropout at 300mA, 35µA quiescent current, 68dB PSRR at 1kHz, and 2% output accuracy, it operates from 2V to 5.5V input. Stable with only 0.1µF output capacitance, it includes enable pin, thermal shutdown, and overcurrent protection, making it ideal for battery-powered and noise-sensitive applications.
