Additional Details

The XC6219B362MR typically supports an input voltage range of 1.8V to 6.0V and delivers a fixed output voltage of 3.6V. It is available in a SOT-25 package. The regulator's low dropout performance is achieved through its optimized internal architecture, which minimizes the voltage drop across the regulator at higher current loads. This feature is particularly important in battery-powered applications where the battery voltage gradually decreases over time. The overcurrent protection feature is designed to limit the output current to a safe level, preventing damage to the regulator and connected devices in the event of a short circuit or overload condition. The thermal shutdown protection feature monitors the regulator's junction temperature and shuts down the regulator when the temperature exceeds a predefined threshold, preventing damage from overheating. The XC6219 series is known for its reliability and is widely used in various portable electronic devices.
