The Microchip High voltage low output current adjustable linear regulator with an operating input voltage range from 13.2V to 100V. The output voltage is adjustable from 1.20V to 88V, requiring at least a 12V difference between input and output. Voltage adjustment is achieved using two external resistors R1 and R2. The LR12 maintains a nominal 1.20V between VOUT and ADJ pins, which is amplified by the resistor ratio. An internal bias current of typically 10 μA is applied to the ADJ pin.
