XC6222D381ER-G

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

The XC6222D381ER-G is a fixed-output low-dropout regulator manufactured by Torex Semiconductor. It provides a stable 3.8 V output with a maximum load current of 700 mA. The device operates within an input voltage range of 1.7 V to 6 V and maintains a typical dropout voltage of 220 mV at 300 mA. Key electrical specifications include a quiescent current of 220 µA, a line regulation of 0.01 %/V, and a power supply rejection ratio of 65 dB at 1 kHz. It features overcurrent protection and is housed in a compact USP-6C-6 package.

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

Verify the specific suffix 'D' indicates the 3.8 V fixed output variant. Confirm the 'ER' suffix corresponds to the USP-6C-6 package type. Ensure RoHS compliance requirements are met for your assembly process. Cross-reference the manufacturer part number with official distributor catalogs to avoid counterfeit components. Check for any specific handling or storage guidelines provided in the datasheet.

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

Select this component when a precise 3.8 V rail is required from a single-cell lithium battery or similar source. The 700 mA capacity suits moderate load applications. Consider the 220 mV dropout voltage against your minimum input voltage constraints. The USP-6C-6 package offers a small footprint for space-constrained designs. Evaluate thermal dissipation needs based on the expected load current and ambient temperature.
