The H7144-1 is a Low Dropout Regulator (LDO) SOT89 RoHS manufactured by Siproin. It is an advanced low dropout voltage regulator which provides excellent regulation performance while keeping quiescent current low. Its regulated output voltage is adjustable between 1.5V and 15V, and it typically achieves a minimum dropout voltage of 0.5V at full load. It supports a maximum output current of 150mA, is capable of operating over a wide temperature range of -40°C to 85°C, and is available in the RoHS compliant and SOT89 packages. It also has extended features such as Low Voltage Operation, Over Voltage/Current Protection, Thermal Shut Down, and Fast Transient Response. The H7144-1 is perfect for applications needing low noise, low dropout, and low quiescent current, such as portable electronic devices, power intensive embedded systems, telecommunications base stations, and notebook computers.
