HT7333A Datasheet PDF – 3.3V, LDO Regulator – HOLTEK

Part Number: HT7333A, HT7333, 7333-A

Function: Low Drop Out Regulator Implemented in CMOS technology

Package: TO-92, SOT-89 Type

Manufacturer: Holtek Semiconductor ( )




The HT7333A series  is a set of three-terminal, low power, high voltage regulators implemented in CMOS technology. The series features extremely low quiescent current which is typically 4μA. They allow input voltages as high as 12V. The device provides large current with a significantly small dropout voltage. The HT7333A consists of a high-precision voltage reference, an error correction circuit, and a current limited output driver.
