S-1312

S-1312 Series www.sii-ic.com © Seiko Instruments Inc., 2011-2014 LOW CURRENT CONSUMPTION HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR Rev.2.3_00 The S-1312 Series, developed by using the CMOS technology, is a positive voltage regulator IC which has low current consumption, high ripple-rejection and low dropout voltage. Even with low current consumption of 20 μA typ., it has high ripple-rejection of 75 dB typ., and a ceramic capacitor of 0.22 μF or more can be used as the input and output capacitors. It also has high-accuracy output voltage of ±1.0%.  Features Output voltage: Input voltage: Output voltage accuracy: Dropout voltage: Current consumption: Output current: Input and output capacitors: Ripple rejection: Built-in overcurrent protection circuit: Built-in thermal shutdown circuit: Built-in ON / OFF circuit: Pull-down resistor is selectable. Discharge shunt function is selectable. Operation temperature range: Lead-free (Sn 100%), halogen-free 1.0 V to 3.5 V, selectable in 0.05 V step 1.5 V to 5.5 V ±1.0% (1.0 V to 1.45 V output product: ±15 mV) 160 mV typ. (2.8 V output product, IOUT = 100 mA) During operation: 20 μA typ., 30 μA max. During power-off: 0.1 μA typ., 1.0 μA max. Possible to output 150 mA (VIN ≥ VOUT(S) + 1.0 V)*1 A ceramic capacitor of 0.22 μF or more can be used. 75 dB typ. (1.2 V output product, f = 1.0 kHz) 70 dB typ. (2.85 V output product, f = 1.0 kHz) Limits overcurrent of output transistor. Prevents d...
