Notes:

12.

Measured under pulsed conditions. Pulse width ≤ 300μs. Duty cycle ≤ 2%

13. Line regulation

∆VOUT = VOUT(@ VIN = 72V) – VOUT(@ VIN = 15V)

14. Load regulation

∆VOUT = VOUT(@ IOUT = 30mA) – VOUT(@ IOUT = 0.1mA)

∆VOUT = VOUT(@ IOUT = 100mA) – VOUT(@ IOUT = 0.1mA)

Notes

VIN

Input Supply

Input voltage can vary from -0.3V to 100V with respect to GND; for VOUT regulated then 15V ≤ VIN ≤ 100V.

It is recommended to connect a 1µF capacitor to GND.

GND

Power Ground

This pin should be tied to the system ground.

VOUT

Voltage Output

Outputs a regulated 12V when 15V ≤ VIN ≤ 100V. When VIN < 15V, then VOUT maximum = VIN – 1.5V.

The pin can be pulled high to a maximum of +18V with respect to GND, or +12V with respect to VIN,

whichever is lower. It is recommended to connect a 10µF capacitor to GND and a minimum of 10µA to be

drawn from VOUT to maintain regulation.
