S-1167 Series ULTRA LOW CURRENT CONSUMPTION, HIGH RIPPLE REJECTION www.ablic.com AND LOW DROPOUT CMOS VOLTAGE REGULATOR www.ablicinc.com ABLIC Inc., 2004-2015 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. Features Output voltage: 1.5 V to 5.5 V, selectable in 0.1 V step Input voltage: 2.0 V to 6.5 V Output voltage accuracy: 1.0% Dropout voltage: 150 mV typ. (3.0 V output product, I = 100 mA) OUT Current consumption: During operation: 9 A typ., 16 A max. During power-off: 0.1 A typ., 0.9 A max. *1 Output current: Possible to output 150 mA (V V 1.0 V) IN OUT(S) Input and output capacitors: A ceramic capacitor of 1.0 F or more can be used. Ripple rejection: 70 dB typ. (3.0 V output product, f = 1.0 kHz) Built-in overcurrent protection circuit: Limits overcurrent of output transistor. Built-in ON / OFF circuit: Ensures long battery life. Operation temperature range: Ta = 40C to 85C *2 Lead-free, Sn 100%, halogen-free *1. Attention should be paid to the power dissipation of the package when the output current is large. *2. Refer to Product Name Structure for details.
