Input in the XC6222B181MR-G is DC voltage in a range of 4.5V to 18V with an output of 3.3V. It has a maximum output current of 1.8A, thermal shut-down, current limiting, and reverse current flow protection. XC6222B181MR-G is the next generation linear voltage regulator and belongs to the PMIC family of Voltage Regulator - Linear category.

The XC6222B181MR-G typically utilizes a voltage divider and no-load power supply technique under the control of a logic unit to achieve the desired output voltage. The input current necessary to achieve the desired output voltage is drawn from the power source, which is then evaluated by a logic unit and determines the feedback, which if high, results in higher output voltage or if low, results in lower output voltage.

The IC contains a control IC that implements the linear voltage regulator, a voltage reference, and a compensation circuit that ensures output voltage stability. The control IC also includes an over-voltage protection circuit, a thermal shut-down, an over current protection, a reverse current flow protection, and an external voltage divider. The IC also contains a PS pin, which is connected to ground and used to sense the differential of the power source.

The XC6222B181MR-G contains an onboard low drop-out (LDO) regulator that regulates input DC voltage to a constant 3.3V output.The XC6222B181MR-G can also be used as a 3-pin voltage regulator with its internal 5V/12V reference. The 5V/12V reference allows the XC6222B181MR-G to regulate an input voltage with a wide range of voltages from 2.5V to 12V, allowing for an output voltage of 3.3V.

XC6222B181MR-G’s thermal shut-down feature protects the IC from overheating. Additionally, an internal current limit prevents damage under severe overload conditions. The device also has a reverse current protection that protects the device from any reverse flow of current. It also has a current limiting circuit that senses excessive output current and limits current flow to maintain the selected output voltage.

XC6222B181MR-G is used in various applications that require a steady output voltage with good efficiency and reliability. In applications such as data converter, telecommunications, interfacing to ICs with 3.3V logic, automotive, and networking applications, the XC6222B181MR-G is a highly reliable, economical and energy-efficient solution.
