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 10?A is connected to the ADJ pin. This increases VOUT by a constant voltage of 10?A times R2. The LR8 has current limiting and temperature limiting. The output current limit is typically 20mA and the minimum temperature limit is 125°C. An output short circuit current will therefore be limited to 20mA. When the junction temperature reaches its temperature limit, the output current and/or output voltage will decrease to keep the junction temperature from exceeding its temperature limit. For SMPS start-up circuit applications, the LR8 turns off when an external voltage greater than the output voltage of the LR8 is applied to VOUT of the LR8. To maintain stability, a bypass capacitor of 1.0?F or larger and a minimum DC output current of 500?A are required. The device is available in TO-243AA (SOT-89), TO-252 (D-PAK), and TO-92 packages.
