HIGH-PRECISION VOLTAGE REGULATOR
S-812XXSG Series
The S-812XXSG Series is a three-terminal positive voltage regulator made using the CMOS process. Since the S-812XXSG Series has higher precision output voltage and consumes less current than existing three-terminal voltage regulators, battery-powered portable equipment can have a higher performance and a longer service life.
Features
Low power consumption (2.5 A max.) High accuracy of output voltage ±2% : VOUT2.7 V ±2.4% : VOUT2.6 V Small input/output voltage difference (S-81250SG: 160 mV typ. IOUT=10 mA) Low temperature coefficient of output voltage (S-81250SG: ±0.625 mV/C typ.) Wide operating voltage range (S-81250SG: 16 V max.) Good line regulation (S-81250SG: 40 mV typ. IOUT=1A to 40 mA) TO-92, SOT-89-3 and SOT-23-5 package
