Technical Specifications

The XC6223B311MR-G has an output voltage of 3.1V. It features a low dropout voltage, allowing it to operate with a small difference between the input and output voltages. The low quiescent current minimizes power consumption. The high ripple rejection ensures a clean output voltage even with noisy input voltages. The overcurrent and thermal shutdown protection mechanisms protect the regulator from damage. Detailed specifications, including the dropout voltage, quiescent current, ripple rejection ratio, and output current capability, can be found in the Torex Semiconductor datasheet.

LDO regulators work by adjusting the internal pass transistor to maintain a constant output voltage, even as the input voltage or load current changes. The XC6223B311MR-G incorporates various protection features to ensure reliable operation. The output voltage is very accurate and stable over temperature.
