TPS3823-50DBVR – TEXAS INSTRUMENTS

The TPS3823-50DBVR is a single-channel, low-dropout (LDO) regulator from Texas Instruments, housed in a tiny 6-pin SOT-23 package. Specifically designed for low-power applications requiring high efficiency, it features a 500mA output current capability and a guaranteed 300mV dropout voltage at full load. Its input voltage range spans 2.5V to 5.5V, enabling flexible power supply integration. The device incorporates a precision enable pin (EN) allowing for power-saving shutdown modes, reducing quiescent current to a mere 20µA. Output voltage is fixed at 3.3V, making it ideal for powering microcontroller cores and other 3.3V logic._x000D_
