he HT7833 TO-92 Package 3.3V LDO is a high-efficiency, low-dropout (LDO) three-terminal positive voltage regulator designed to convert higher input voltages into a stable, fixed 3.3V DC output. Operating with ultra-low quiescent current and low dropout voltage, it provides an ideal power supply solution for power-sensitive and battery-operated microcontroller applications.
Housed in a compact, through-hole 3-pin TO-92 package, the HT7833 features integrated short-circuit current protection and thermal shutdown circuitry to safeguard your circuit against accidental overcurrent or excessive power dissipation. It can supply up to 500mA of continuous output current, making it a robust upgrade over standard regulators for powering wireless transceivers and low-voltage ICs.
The HT7833 is widely used to power 3.3V microcontrollers, Wi-Fi modules, and low-power sensors directly from 5V USB buses, 6V battery packs, or regulated DC rails. It plugs easily into breadboards, stripboards, perfboards, and custom printed circuit boards (PCBs) and is fully compatible with ESP8266, ESP32, STM32, Raspberry Pi Pico, and 3.3V sensor interfaces.
