XC6227C471ER-G

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

The XC6227C471ER-G is a fixed-output low dropout regulator from Torex Semiconductor, providing a stable 4.7 V output with a maximum continuous current of 700 mA. It operates within an input voltage range of 1.7 V to 6 V and maintains a typical dropout voltage of 120 mV. The device features a quiescent current of 100 uA and offers high ripple rejection of 65 dB at 1 kHz. Voltage regulation accuracy is specified at 1%, with line regulation at 0.01 %/V and load regulation at 50 mV. Power dissipation reaches 250 mW, and it functions reliably across a temperature range of -40°C to +85°C in a SOT-25-5 package.

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

Verify the specific suffix ER-G against the official Torex datasheet to confirm the SOT-25-5 package and tape-and-reel packaging format. Ensure that the required output voltage of 4.7 V matches the design specifications precisely, as other variants in the XC6227 series offer different fixed voltages. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement orders.

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

Select this component when a fixed 4.7 V rail is required with high current capability up to 700 mA. The low dropout characteristic makes it suitable for applications where the input voltage is close to the output level. Consider the 100 uA static current for battery life optimization. Verify that the SOT-25-5 package fits the PCB layout constraints and that the thermal dissipation requirements are met within the operating temperature range.

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

This part belongs to the XC6227 series of high-speed LDO regulators designed by Torex Semiconductor. The series is characterized by high accuracy, low noise, and integrated protection features. The XC6227C471ER-G specifically denotes the 4.7 V output variant in the SOT-25-5 surface-mount package, distinguishing it from other output voltages and package types within the same family.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Other parts in the XC6227 series with different output voltages may serve as functional substitutes if the voltage requirement changes. Variants such as XC6227C331MR-G or XC6227C501PR-G offer similar electrical characteristics but differ in output voltage and package type. Direct pin-to-pin replacement requires matching the package style and ensuring the new output voltage aligns with the system design.
