It is capable of delivering up to 100 mA of load current with very stable output voltage.

Working Principle of ADP2138ACBZ-0.8-R7

The ADP2138ACBZ-0.8-R7 DC-DC switching regulators operate by controlling the output voltage in response to changes in load current and input voltage. The device includes a voltage regulator that controls the switching of two transistors to regulate the output voltage. When the load current increases, the voltage regulator increases the duty cycle, or amount of time that the switching transistors are in the "on" state. This causes the output voltage to rise. When load current decreases, the duty cycle is reduced and the output voltage drops. This closed-loop system ensures that the output voltage remains stable regardless of the input voltage or load current.
