The HT75A0-1 is a low dropout regulators (LDO) manufactured by Holtek in a SOT-89 RoHS package. It is a low voltage, low noise, low dropout voltage, and fast transient response LDO with overcurrent protection. It offers an output voltage of 0.8V to 10V and input voltage of 4.5V to 12V, with an operating temperature range of -40 to 85°C. It has a low dropout voltage of 800mV max, and a low output noise of less than 30µVRMS. It also features a fast transient response, overcurrent protection and output voltage accuracy of ±1.5%. These features make the HT75A0-1 ideal for applications such as portable radios, mobile phones, MP3 players, PDA, digital camera and LCD drivers.
