5.5 V Input, 200 mA, Output Capacitor-less Voltage Regulator S-1315 Series

The S-1315 Series, developed by using the CMOS technology, is a positive voltage regulator IC of 200 mA output current which has low dropout voltage, high-accuracy output voltage and low current consumption. The S-1315 Series enables high density mounting due to output capacitor-less.
The current consumption is extremely low as 7 μA typ., and even without an output capacitor, it realizes high-speed response.
It also has high-accuracy output voltage of ±1.0%.


Output voltage
1.0 V to 4.2 V, selectable in 0.05 V step
Input voltage
1.4 V to 5.5 V
Output voltage accuracy
±1.0% (1.0 V to 1.45 V output product: ±15 mV)
Dropout voltage
224 mV typ. (3.0 V output product, Iout = 200 mA)
Current consumption
During operation: 7 µA typ., 13 µA max.
During power-off: 0.1 µA typ., 1.0 µA max.
Output current
Possible to output 200 mA (Vin ≥ VOUT(S) + 1.0 V)*1
Input and output capacitor
A ceramic capacitor of 0.1 µF or more can be used for the input capacitor.
Output capacitor is unnecessary, or a ceramic capacitor of 10 µF or less can be used.
Ripple rejection
65 dB typ. (1.0 V output product, f = 1.0 kHz)
60 dB typ. (2.8 V output product, f = 1.0 kHz)
Built-in overcurrent protection circuit
Limits overcurrent of output transistor.
Built-in ON / OFF circuit
Ensures long battery life.
Discharge shunt function “available” / “unavailable” is selectable.
Pull-down function “available” / “unavailable” 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.
