Low Dropout LDO (USB2)
Part number: S-1170B50UC-OUJTFG
Sharp code: VHIS170B50U-1Y
http://datasheet.sii-ic.com/en/voltage_regulator/S1170_E.pdf
The S-1170 Series is a positive voltage regulator with a low dropout voltage (LDO), high output voltage accuracy, and low current
consumption developed based on CMOS technology. .
A built-in low on-resistance transistor provides a low dropout voltage and large output current, a built-in overcurrent protector
prevents the load current from exceeding the current capacitance of the output transistor, and a built-in thermal shutdown circuit
prevents damage caused by the heat. An ON/OFF circuit ensures a long battery life. Compared with the voltage regulators using the
conventional CMOS process, a larger variety of capacitors are available, including small ceramic capacitors. Small SOT-89-5 and
6-Pin HSON(A) packages realize high-density mounting.
