S-1312 Series

LOW CURRENT CONSUMPTION HIGH RIPPLE-REJECTION

LOW DROPOUT CMOS VOLTAGE REGULATOR

www.sii-ic.com

Rev.2.3_01

The S-1312 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 μA typ., it has high ripple-rejection of 75 dB typ., and a ceramic capacitor of 0.22 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:

• Input voltage:

1.0 V to 3.5 V, selectable in 0.05 V step

1.5 V to 5.5 V

• Output voltage accuracy:

• Dropout voltage:

• Current consumption:

1.0% (1.0 V to 1.45 V output product: 15 mV)

160 mV typ. (2.8 V output product, I_OUT= 100 mA)

During operation:

During power-off:

20 μA typ., 30 μA max.

0.1 μA typ., 1.0 μA max.

• Output current:

• Input and output capacitors:

• Ripple rejection:

Possible to output 150 mA (V_IN≥ V_OUT(S)+ 1.0 V)^*1

A ceramic capacitor of 0.22 μF 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.

• Built-in overcurrent protection circuit:

• Built-in thermal shutdown circuit:

• Built-in ON / OFF circuit:

Ensures long battery life.

• Pull-down resistor is selectable.

• Discharge shunt function is selectable.

• Operation temperature range:

• Lead-free (Sn 100%), halogen-free

Ta = −40°C to +85°C

*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 appliance

 Packages

• SOT-23-5

• HSNT-4 (1010)

• HSNT-4 (0808)
