Automotive, 125°C Operation, 36 V Input, 1000 mA Voltage Regulator S-19214 Series


S-19213 Series  (500mA) | S-19214 Series  (1000mA)

The S-19214 Series developed by using high-withstand voltage CMOS process technology, is a positive voltage regulator with a high-withstand voltage, low current consumption and high-accuracy output voltage.
The S-19214 Series operates at the maximum operation voltage of 36 V and a low current consumption of 5.0 μA typ. and has a built-in low on-resistance output transistor, which provides a very small dropout voltage and a large output current.
In addition to the type in which output voltage is set inside the IC, the type for which output voltage can be set via an external resistor is added to a lineup. 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.

Thermal simulation service
ABLIC Inc. offers a “thermal simulation service” which supports the thermal design in conditions when our power management ICs are in use by customers. Our thermal simulation service will contribute to reducing the risk in the thermal design at customers development stage.

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.
