S-1167B29-M5T1U

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 μA typ., the S-1167 Series realized the 70 dB of high ripple rejection rate. Besides, a ceramic capacitor of 1.0 μF 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-onresistance 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.
