∆V_OUT = V_OUT(@ V_IN = 72V) – V_OUT(@ V_IN = 15V)
∆V_OUT = V_OUT(@ I_OUT = 30mA) – V_OUT(@ I_OUT = 0.1mA)
∆V_OUT = V_OUT(@ I_OUT = 100mA) – V_OUT(@ I_OUT = 0.1mA)

Notes
To maintain output regulation the input voltage can vary from 15V to 100V with respect to the GND pin. It is
recommended to connect a 1µF capacitor to GND.
This pin should be tied to the system ground.
Outputs a regulated 12V. It is recommended to connect a 10µF capacitor to GND. Minimum of 10µA must
be drawn from V_OUT to maintain regulation. The pin can be pulled high to a maximum of 18V with respect to
ground.
