105C OPERATION LOW CURRENT CONSUMPTION
HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR
The S-1312xxxH 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 A typ., it has high ripple-rejection of 75 dB typ., and a ceramic capacitor of 0.22 F
or more can be used as the input and output capacitors.
It also has high-accuracy output voltage of 1.0%.
Output voltage accuracy:
Input and output capacitors:
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 A typ., 30 A max.
During power-off: 0.1 A typ., 1.0 A max.
Possible to output 150 mA (VIN VOUT(S) 1.0 V)*1
A ceramic capacitor of 0.22 F 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 damage caused by heat.
Ensures long battery life.
Ta = 40°C to 105°C
*1. Please make sure that the loss of the IC will not exceed the power dissipation when the output current is large.
