SUPER LOW CURRENT CONSUMPTION
LOW DROPOUT CMOS VOLTAGE REGULATOR
Rev.2.0_00
The S-1313 Series, developed by using the CMOS technology, is a positive voltage regulator IC which has the super low
current consumption and the low dropout voltage.
Current consumption is as low as 0.9 μA typ., and a ceramic capacitor of 0.1 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:
1.0 V to 3.5 V, selectable in 0.05 V step.
Input voltage:
1.5 V to 5.5 V
Output voltage accuracy:
±1.0% (1.0 V to 1.45 V output product: ±15 mV)
Dropout voltage:
170 mV typ. (2.8 V output product, IOUT = 100 mA)
Current consumption:
During operation: 0.9 μA typ., 1.35 μA max.
Output current:
During power-off: 0.01 μA typ., 0.1 μA max.
Possible to output 200 mA (VOUT(S) 1.4 V, VIN VOUT(S) + 1.0 V)*1
Input and output capacitors:
A ceramic capacitor of 0.1 μF or more can be used.
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.
Discharge shunt function is selectable.
Operation temperature range:
Ta = 40°C to +85°C
Lead-free (Sn 100%), halogen-free
*1. Attention should be paid to the power dissipation of the package when the output current is large.
Applications
Constant-voltage power supply for portable communication device, digital camera, and digital audio player
Constant-voltage power supply for battery-powered device
Constant-voltage power supply for home electric / electronic appliance
