The Supertex LR12K4-G is a versatile adjustable linear regulator designed for high voltage applications. It operates with an input voltage range from 13.2V to 100V and allows for an adjustable output voltage from 1.20V to 88V. This regulator is stable with a 100nF output capacitor and requires a minimum DC output current of 500µA for stability.
Key features include a 5% reference voltage tolerance, output current limiting up to 100mA, and over-temperature protection. The output voltage is set using two external resistors, R1 and R2, with an internal bias current of typically 10µA. The device is available in multiple package options: TO-252, 8-Lead SOIC, and TO-92.
Applications for the LR12K4-G include DC/DC SMPS startup circuits, adjustable high voltage constant current sources, industrial controls, motor controls, battery-powered systems, power supplies, telecom applications, LED drivers, and automotive applications.
The input voltage range is 13.2V to 100V.
The output voltage is adjustable from 1.20V to 88V, provided the input voltage is at least 12V greater than the output voltage.
The output current is limited to 100mA maximum.
The operating ambient temperature range is -40°C to +85°C.
The LR12K4-G is available in TO-252, 8-Lead SOIC, and TO-92 packages.
The input voltage must be at least 12V greater than the output voltage.
Yes, a 100nF output capacitor is required for stability.
