●The S-1167 Series is a positive voltage regulator with ultra low current consumption, high ripple rejection, low drop voltage and high output voltage accuracy developed based on CMOS technology.
●Although current consumption is very small with 9 µA typ., S-1167 Series realized the 70 dB of high ripple rejection rate. Besides a 1.0 µF ceramic capacitor is available as an input-and-output capacitor.
●Moreover, dropout voltage is also small since output voltage accuracy realizes ±1.0% of high accuracy, and the low-on-resistance transistor is built-in. A built-in Output current protector prevents the load current from exceeding the current capacitance of the output transistor. A shutdown circuit ensures long battery life.
