XC6221A49A7R-G

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

The XC6221A49A7R-G is a fixed-output low dropout regulator from Torex Semiconductor, housed in a USPN-4 package. It provides a nominal output voltage of 4.95V with a maximum continuous output current of 200mA. The device operates within an input voltage range of 1.6V to 6.0V and features a typical dropout voltage of 80mV at 100mA load. Electrical characteristics include a standard output accuracy of +2% for voltages above 1.50V, a supply current of 25μA, and a standby current of 0.01μA. Ripple rejection is rated at 70dB at 1kHz.

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

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

Verify the specific suffix '7R-G' corresponds to the USPN-4 package configuration and reel order quantity as defined in the official datasheet. Confirm that the 'A' designation indicates the absence of an internal pull-down resistor on the CE pin. Ensure compliance requirements match the Halogen and Antimony-free status associated with the '-G' suffix.

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

Select this component when a fixed 4.95V rail is required in ultra-small form factor designs. The USPN-4 package supports minimal footprint constraints compared to larger alternatives. Consider the lack of an internal CE pull-down resistor if the control signal requires specific biasing or open-state handling during system initialization.
