SUPER-SMALL PACKAGE 2-CIRCUIT BUILT-IN DELAY FUNCTION
HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR
Rev.1.1_00
The S-13D1 Series, developed by using the CMOS technology, is a 2-channel positive voltage regulator IC which has low
dropout voltage, high accuracy output voltage and low current consumption.
A 0.22 μF small ceramic capacitor can be used, and the S-13D1 Series includes a load current protection circuit that
prevents the output current from exceeding the current capacitance of the output transistor and a thermal shutdown circuit
that prevents damage due to overheating. Also, C / F type in the S-13D1 Series has a built-in delay function that sets the
difference of rising time in a channel.
„ Features
Output voltage:
1.0 V to 3.6 V, selectable in 0.05 V step
Low equivalent series resistance capacitor: A ceramic capacitor of 0.22 μF or more can be used for the output
capacitor.
Input voltage:
1.5 V to 5.5 V
High-accuracy output voltage:
±1.0% (1.0 V to 1.45 V output product :±15 mV)
Dropout voltage:
Low current consumption:
80 mV typ. (2.8 V output product, IOUT = 100 mA)
During operation: 39 μA typ., 58 μA max. (per circuit)
High output current:
High ripple rejection:
During power-off: 0.1 μA typ., 1.0 μA max.
Possible to output 150 mA (at VIN VOUT(S) + 1.0 V)*1 (per circuit)
70 dB typ. (3.6 V output product, at f = 1.0 kHz)
Built-in overcurrent protection circuit:
Limits overcurrent of output transistor.
Built-in thermal shutdown circuit:
Prevents damage caused by heat.
Built-in ON / OFF circuit:
Ensures long battery life.
Constant current source pull-down is selectable.
