The S-19315 Series, developed by using high-withstand voltage CMOS process technology, is a positive voltage regulator with the reset function, which has high-withstand voltage and low current consumption.
Apart from the power supply pin, the detection voltage input pin (SENSE pin) is also prepared for the reset function, so the output is stable even if the SENSE pin falls to 0 V. The output form is Nch open-drain output.

Parts List

U(Ux), S and G at the end of the product name of ABLIC Inc. were used to indicate different material specifications as “environmental code”,
however, these have now been unified into “lead-free and halogen-free” and are identical in terms of environmental quality.
Note: Lead-free plating other than 100% Sn is applied to some limited old products, therefore, please contact our sales representatives for details.
These descriptions may be different from the actual product name and parameter.
Please confirm the product name and specifications with the data sheet again.
