S-19252 Datasheet, Specifications, Parts list and Support

The S-19252 Series, developed by using CMOS process technology, is a positive voltage regulator with high-accuracy output voltage which incorporates the soft-start function. This IC has high ripple-rejection of 80 dB typ., and operates with low current consumption of 36 μA typ. The S-19252 Series incorporates the soft-start function to adjust the rising time of output voltage immediately after power-on or after the ON / OFF pin is set to ON. It also has a built-in overcurrent protection circuit to limit overcurrent of output transistor. In addition to the conventional small packages SOT-23-5 and SC-82AB, the super-small package HSNT-4(1010)B is added to the lineup, which realizes higher-density mounting.

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.
