FP115
Dual OPA Circuit with Precision Shunt Regulator
General Description
The FP115 incorporates dual operation amplifier and a precision shunt regulator (typ. 1.25V). The
main function of FP115 is CV control and OC sense for low power RCC circuits. The small package
SOT-23-5L is suitable for mini-size AC-DC power supply or adapter applications.

Function Description
Internal Reference Regulator
The FP115 includes a 1.25V high precision shut regulator to reduce application circuit external
part number. This 1.25V reference voltage is divided down by resistor string to 156mV then connects
to OPA1 and OPA2’s non-inverting input for comparison. Applications with VCC voltage higher than 20V
are not suitable for this chip as an internal 2KΩ resistor which connected between Vcc and 1.25V
reference will draw too much current and increase power loss.

For example:
If VCC is 6V, the power loss of the 2KΩ resistor is (6-1.25)2/2KΩ=11.3mW. When VCC is 12V, the
power loss of the 2KΩ resistor is (12-1.25)2/2KΩ=57.8mW.
