HSNT-4(0808)B (PK004-B)

HSNT-4(1010)B (PL004-B)

The S-19251 Series, developed by using CMOS process technology, is a positive voltage regulator with a low current consumption, high ripple-rejection and high-accuracy output voltage.
This IC has high ripple-rejection of 75 dB typ., and operates with low current consumption of 20 μA typ.
Also, a built-in overcurrent protection circuit to limit overcurrent of the output transistor and a built-in thermal shutdown circuit to limit heat are included. In addition to the conventional package SOT-23-5, the super-small packages HSNT-4(1010)B and HSNT-4(0808)B are 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.
