S-1312 Series, developed by using the CMOS technology, is a positive voltage regulator IC which has the low current
consumption, the high ripple-rejection and the low dropout voltage.
Even with low current consumption of 20
μA typ., it has high ripple-rejection of 75 dB typ., and ceramic capacitor of 0.22 μF
or more can be used as the input and output capacitor.
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
High-accuracy output voltage:
±1.0% (1.0 V to 1.45 V output product : ±15 mV)
Dropout voltage:
160 mV typ. (products having the output of 2.8 V, IOUT
= 100 mA)
Low current consumption:
During operation:
20
μA typ., 30 μA max.
During power-off:
0.1
μA typ., 1.0 μA max.
High output current:
Possible to output 150 mA (at VIN
≥ VOUT(S) + 1.0 V)
*1
Low equivalent series resistance capacitor: A ceramic capacitor of 0.22 μF or more can be used for the output
capacitor.
High ripple rejection:
75 dB typ. (products having the output of 1.2 V, at f
= 1.0 kHz)
70 dB typ. (products having the output of 2.85 V, 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.
Pull-down resistor is selectable.
Discharge shunt circuit is selectable.
Lead-free (Sn 100%), halogen-free
*2
*1. Attention should be paid to the power dissipation of the package when the output current is large.
*2. Refer to “ Product Name Structure” for details.
Applications
Constant-voltage power supply for portable communication devices, digital cameras, and digital audio players
Constant-voltage power supply for battery-powered devices
Constant-voltage power supply for home electric / electronic appliances
Packages
