S-1167

Rev.2.3_00 ULTRA LOW CURRENT CONSUMPTION, HIGH RIPPLE REJECTION AND LOW DROPOUT CMOS VOLTAGE REGULATOR www.datasheet4u.com 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. „ Features Output voltage : 1.5 to 5.5 V, selectable in 0.1 V steps. Low equivalent series resistance capacitor can be used : A ceramic capacitor of 1.0 µF or more can be used for the output capacitor. Wide input voltage range : 2.0 to 6.5 V High-accuracy output voltage : ±1.0% Low dropout voltage : 150 mV typ. (3.0 V output product, at IOUT = 100 mA) Lo...
