Rev.1.3_00

The S-1740/1741 Series, developed using CMOS technology, is a positive voltage regulator with the supply voltage divided

output, which features super low current consumption and low dropout voltage.

The regulator block has low current consumption of 0.35 μA typ. and high-accuracy output voltage of 1.0%.

The function of the supply voltage divided output is prepared in the S-1740/1741 Series. The supply voltage divided output is

a function that divides the input voltage (V_IN) of the regulator into V_IN/2 or V_IN/3 and outputs the voltage. For example, this

function makes it possible that the IC connects to a low voltage microcontroller A/D converter directly and the microcontroller

monitors a battery voltage.

 Features

Regulator block

• Output voltage:

• Input voltage:

V_OUT= 1.0 V to 3.5 V, selectable in 0.05 V step

_IN= 1.5 V to 5.5 V

• Output voltage accuracy:

• Dropout voltage:

1.0% (1.0 V to 1.45 V output product: 15 mV) (Ta = +25°C)

20 mV typ. (2.5 V output product, at I_OUT= 10 mA) (Ta = +25°C)

• Current consumption during operation:

• Output current:

• Input capacitor:

• Output capacitor:

• Built-in overcurrent protection circuit:

I_SS1= 0.35 μA typ. (Ta = +25°C)

Possible to output 100 mA ( at V_IN≥ V_OUT(S)+ 1.0 V)^*1

A ceramic capacitor can be used. (1.0 μF or more)

A ceramic capacitor can be used. (1.0 μF to 100 μF)

Limits overcurrent of output transistor.

Supply voltage divider block

• Output voltage:

_PMOUT= V_IN/2 (S-1740 Series)

_PMOUT= V_IN/3 (S-1741 Series)

•

Current consumption during operation

I_SS1P= 0.15 μA typ. (Ta = +25°C)

• Output capacitor:

A ceramic capacitor can be used. (100 nF to 220 nF)

• Built-in enable circuit:

Ensures long battery life.

Overall

• Operation temperature range:

• Lead-free (Sn 100%), halogen-free

Ta = −40°C to +85°C

*1. Please make sure that the loss of the IC will not exceed the power dissipation when the output current is large.

 Applications
