S-1167 Series
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. Two packages, SOT-23-5 and SNT-6A(H), are available. Compared with the
voltage regulators using the conventional
CMOS process, S-1167 Series is the most suitable for the portable equipments with ultra low current consumption and corresponding to the small package.
