Function : High Input Voltage, Adjustable 3-Terminal Linear Regulator
Производитель : Supertex Inc
The Supertex LR8 is a high voltage, low output current, adjustable linear regulator. It has a wide operating input voltage range of 13.2- 450V. The output voltage can be adjusted from 1.20- 440V provided that the input voltage is at least 12V 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 circuits. The LR8 regulates the voltage difference between VOUT and ADJ pins to a nominal value of 1.20V. The 1.20V is amplified by the external resistor ratio R1 and R2. An internal constant bias current of typically 10µA is connected to the ADJ pin. This increases V OUT by a constant voltage of 10µA times R2.
