The HT7833 3.3V 500mA Low Dropout Voltage is a high-efficiency, surface-mount low-dropout (LDO) three-terminal fixed positive voltage regulator designed to deliver a steady 3.3V DC rail from higher input voltages. Housed in a miniature SOT-89 footprint, this SMD regulator is designed for space-conscious circuit designs requiring high thermal performance in a small form factor.
Featuring a low dropout voltage and low quiescent current, the HT7833-SOT89 easily handles up to 500mA of continuous output current. It includes internal short-circuit current limiting and thermal overload protection, guarding connected microcontrollers and radio modules against accidental power faults.
This SOT-89 SMD regulator is widely used to power 3.3V microcontrollers, Wi-Fi/Bluetooth transceivers, and low-power digital sensors directly from 5V USB buses or lithium battery supplies. It is fully compatible with surface-mount custom PCBs, break-out adapter boards, and development platforms like ESP8266, ESP32, STM32, and Raspberry Pi Pico.
