Product Details

Demonstration circuit 1238B features the LTM8021, a 36V 500mA step-down μModule^® regulator. The output has been preset to 5V by a single resistor within the LTM8021’s output voltage range of 0.8V to 5V. An adjustable soft-start period may be implemented with the addition of a capacitor at C3. The input voltage range is from 7.5V to 36V for the default operating conditions. The LTM8021 may need more input voltage to start up than to run in steady state.
