6.5 V Input, 300 mA Voltage Regulator S-1132 Series

The S-1132 Series is a positive voltage regulator with a low dropout voltage (LDO), high output voltage accuracy, and low current consumption (300 mA output current) developed based on CMOS technology. A 0.1 µF small ceramic capacitor can be used. It operates with low current consumption of 20 µA typ. A built-in Output current protector prevents the load current from exceeding the current capacitance of the output transistor. Compared with the conventional 300 mA output current CMOS voltage regulators, high-density mounting is realized by using the super-small SNT-6A(H) package and a 0.1 µF small ceramic capacitor. Also, the low current consumption makes the S-1132 series ideal for mobile devices.

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.
