XC6221B2227R-G

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The XC6221B2227R-G is a fixed-output low dropout regulator from Torex Semiconductor, housed in a USPN-4 package. It provides a nominal output voltage of 2.2V with a maximum output current of 200mA. The device operates within an input voltage range of 1.6V to 6.0V and features a typical standby current of 0.01μA. It includes a built-in charge leakage circuit for the output capacitor when disabled. The unit meets EU RoHS standards and is halogen-free.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrates a CL auto-discharge function that rapidly pulls the output voltage to the VSS level upon shutdown via the CE pin.
• Utilizes laser trimming technology to achieve precise factory-set output voltage increments without external resistors.
• Operates stably using only low ESR ceramic capacitors for phase compensation.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix '7R-G' confirms the USPN-4 package type and reel quantity. Ensure the 'B' designation matches the requirement for the internal charge leakage circuit. Confirm the '22' code corresponds to the required 2.2V output voltage setting before finalizing procurement orders.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a compact footprint is required alongside fast discharge capabilities. The B-type variant is necessary if rapid output voltage decay is needed during standby mode. Verify that the 2.2V output aligns with the load requirements and that the operating temperature range covers the intended application environment.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the XC6221 series of high-speed CMOS LDO regulators. The series is characterized by low power consumption and high ripple rejection rates. The XC6221B2227R-G specifically utilizes the ultra-small USPN-4 package, distinguishing it from other variants that may use SOT-25 or SSOT-24 packages.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

How does the XC6221B2227R-G handle output voltage when the CE pin is set to low?

Due to the 'B' designation, the IC activates an internal N-channel transistor and auto-discharge resistance. This actively discharges the electric charge stored in the output capacitor, causing the VOUT pin to quickly return to the VSS level.

What is the purpose of the '7R-G' suffix in the part number?

The '7R-G' suffix indicates that the device is packaged in the USPN-4 format and supplied in reels. The '-G' suffix further specifies that the product is compliant with EU RoHS directives and is free from halogens and antimony.
