ULTRA LOW CURRENT CONSUMPTION, HIGH RIPPLE REJECTION
AND LOW DROPOUT CMOS VOLTAGE REGULATOR
Rev.3.2_02
The S-1167 Series is a positive voltage regulator with ultra low current consumption, high ripple rejection, low dropout
voltage and high-accuracy output voltage developed based on CMOS technology.
Although current consumption is very small with 9 A typ., the S-1167 Series realized the 70 dB of high ripple rejection rate.
Besides, a ceramic capacitor of 1.0 F can be used as the input and output capacitors.
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 overcurrent protection circuit prevents that the load current from exceeding the
current capacity of the output transistor. The ON / OFF 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 technology, the S-1167 Series is the most suitable for
the portable equipments with ultra low current consumption and corresponding to the small package.
