S-1315

S-1315 Series www.sii-ic.com © Seiko Instruments Inc., 2011-2014 LOW CURRENT CONSUMPTION OUTPUT CAPACITOR-LESS CMOS VOLTAGE REGULATOR Rev.1.2_00 The S-1315 Series, developed by using the CMOS technology, is a positive voltage regulator IC of 200 mA output current which has low dropout voltage, high-accuracy output voltage and low current consumption. The S-1315 Series enables high density mounting due to output capacitor-less. The current consumption is extremely low as 7 μA typ., and even without an output capacitor, it realizes high-speed response. It also has high-accuracy output voltage of ±1.0%.  Features Output voltage: 1.0 V to 4.2 V, selectable in 0.05 V step Input voltage: 1.4 V to 5.5 V Output voltage accuracy: ±1.0% (1.0 V to 1.45 V output product: ±15 mV) Dropout voltage: Current consumption: 224 mV typ. (3.0 V output product, IOUT = 200 mA) During operation: 7 μA typ., 13 μA max. Output current: Input and output capacitors: During power-off: 0.1 μA typ., 1.0 μA max. Possible to output 200 mA (VIN ≥ VOUT(S) + 1.0 V)*1 A ceramic capacitor of 0.1 μF or more can be used for the input capacitor. Output capacitor is unnecessary, or a ceramic capacitor of 10 μF or less can be used. Ripple rejection: 65 dB typ. (1.0 V output product, f = 1.0 kHz) 60 dB typ. (2.8 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. ...
