measurement is not guaranteed to precisely track transient power excursions in the power device. The internal

thermal shutdown sensor is designed to keep the LT3074 within its safe operating area.

The VIOC buffer outputs a voltage equal to VIN− VOUT+ 800mV. See the Applications Information section for

further information. The VIOC pin’s source current should be set between 10µA and 200µA. The minimum

voltage required from BIAS to VIOC is 1V.

Adding a capacitor at the SETCAP pin decreases output voltage noise. Adding this capacitor bypasses the

reference resistor’s thermal noise as well as the reference current’s noise. The output noise then equals the

error amplifier noise. Use of a SETCAP pin bypass capacitor also increases start-up time.
