Product Description

HT7333 3.3V Voltage Regulator IC TO-92

Ultra-Low Power LDO Voltage Regulator

The HT7333 is a highperformance, lowpower, positive voltage regulator IC that delivers a stable 3.3V output. Fabricated using advanced CMOS technology, it features an ultralow quiescent current and a low dropout voltage, making it an ideal choice for batterypowered and portable electronic devices [citation:1][citation:5].

Delivers a stable 3.3V output with up to 250mA of current [citation:5]
Features an ultra-low quiescent current of 1.5µA to 4µA [citation:1][citation:10]
Maximum input voltage is 12V - do not exceed to prevent damage [citation:3]
