General Description
The Supertex LR8 is a high
voltage, low output current, adjustable linear regulator.
It has a wide operating input
voltage range of 12V to 450V.
The output
voltage can be adjusted from 1.
20V to 440V provided that the input
voltage is at least 10V greater than the output
voltage.
The output
voltage can be adjusted by means of two external resistors R1 and R2 as shown in the typical application circ...
