S-1740/1741 Series

POWER MONITORING OUTPUT,

5.5 V INPUT, 100 mA CMOS VOLTAGE REGULATOR

WITH 0.5

A SUPER LOW CURRENT CONSUMPTION

www.sii-ic.com

Rev.1.2_00

The S-1740/1741 Series, developed using CMOS technology, is a positive voltage regulator with a power monitoring 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 power monitoring output is prepared in the S-1740/1741 Series. The power monitoring 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

V_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.

Power monitor 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
