ULTRA-LOW CURRENT CONSUMPTION 150 mA VOLTAGE REGULATOR WITH BUILT-IN HIGH-ACCURACY VOLTAGE DETECTOR AND RESET INPUT FUNCTION
S-1702 Series
Explanation of Terms
1. Regulator block
1. 4 Line regulation
1. 2 Low ESR
1. 3 Output voltage (V
1. 5 Load regulation (∆V
1. 6 Dropout voltage (V
1. 1 Low dropout voltage regulator
The accuracy of the output voltage is ensured at ±1.0% under the specified conditions of fixed input voltage
output current, and fixed temperature.
*1. Differs depending on the product.
Caution
Indicates the dependency of the output voltage on the input voltage. That is, the values show how much the output
voltage changes due to a change in the input voltage with the output current remaining unchanged.

This IC’s voltage regulator has the low dropout voltage due to its built-in transistor with low on-resistance.
A capacitor whose ESR (Equivalent Series Resistance) is low. The S-1702 Series enables use of a low ESR
capacitor, such as a ceramic capacitor, for the output-side capacitor (C
can be used.
