Additional Details

The XC6204B392MR provides a fixed output voltage of 3.9V. The input voltage range is typically from 2.0V to 6.0V. The low dropout voltage characteristic allows the regulator to maintain its output voltage even when the input voltage is only slightly higher than the output voltage. The low quiescent current minimizes power consumption when the regulator is not actively supplying current to the load. This LDO regulator includes built-in short circuit and over current protection mechanisms to safeguard against potential component failures. It commonly comes in small surface mount packages such as SOT-25. The device operates within a temperature range of -40°C to +85°C.
