5.5 V Input, 150 mA, 2-circuit Voltage Regulator with Delay Function S-13D1 Series

The S-13D1 Series, developed by using the CMOS technology, is a 2-channel positive voltage regulator IC which has low dropout voltage, high accuracy output voltage and low current consumption.
A 0.22 µF small ceramic capacitor can be used, and the S-13D1 Series includes a load current protection circuit that prevents the output current from exceeding the current capacitance of the output transistor and a thermal shutdown circuit that prevents damage due to overheating. Also, C / F type in the S-13D1 Series has a built-in delay function that sets the difference of rising time in a channel.

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.
