REFERENCE CIRCUIT EXAMPLE
Four-time booster circuit
This example drives the booster circuit only, boosts the VIN input voltage four times in negative direction, and
outputs it at the VOUT pin. However, this does not have a voltage regulator and the voltage at VOUT pin may have
a ripple.

Four-time booster and regulator circuits
This example receives a boost output from VOUT pin, stabilizes it via the voltage regulator circuit, and outputs
a voltage having the temperature gradient at VREG pin via the temperature gradient selector circuit.
