The S-1165 series is a low voltage drop, high precision output voltage, low power consumption positive voltage type voltage regulator developed using CMOS technology. The low on-resistance transistor inside makes the voltage drop low, and can obtain a large output current. To prevent the load current from exceeding the output transistor's current capacity, an overcurrent protection circuit is built in. In addition, a power on/off control circuit is built in to extend battery life. Due to the SOT-23-5 small package, it can be installed with high density.
The S‑1165 series is a low‑dropout, high‑precision CMOS voltage regulator developed by Seiko Instruments. It offers selectable output voltages from 1.5 V to 5.5 V in 0.1 V steps, with low quiescent current and built‑in overload protection, making it suitable for battery‑powered devices, communications equipment, and portable electronics.
The device is supplied in a compact SOT‑23‑5 package, providing up to 200 mA of output current. Key electrical characteristics include a typical dropout voltage of 140 mV at 200 mA, ripple suppression of 70 dB at 1 kHz, and a quiescent current of 0.1 mA in standby mode.
