XC6221A14AMR-G

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

The XC6221A14AMR-G is a fixed-output low dropout regulator from Torex Semiconductor, housed in an SOT-25 package. It provides a nominal output voltage of 1.40V with a standard accuracy tolerance of ±2% for voltages above 1.50V or ±30mV for lower outputs. The device supports a maximum output current of 200mA and operates within an input voltage range of 1.6V to 6.0V. Key electrical characteristics include a typical supply current of 25μA, a standby current of 0.01μA, and a ripple rejection rate of 70dB at 1kHz. The component functions reliably across an ambient temperature range of -40℃ to +85℃.

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

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

Verify the specific ordering suffix against official documentation to confirm package type and environmental compliance status. Ensure the selected variant matches the required output voltage increment and accuracy class for the target application. Confirm RoHS and halogen-free specifications are met according to the manufacturer's latest product classification data before finalizing procurement.

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

Select this regulator when a fixed 1.40V output is required with standard accuracy tolerances. Consider the SOT-25 package for surface-mount assembly constraints. Evaluate the 200mA current capability against peak load requirements. Verify that the input voltage remains within the specified operational range to maintain regulation and minimize dropout effects during system operation.

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

This component belongs to the XC6221 series of high-accuracy, low-noise, high-speed LDO regulators manufactured by Torex Semiconductor. The series utilizes laser trimming technology to set output voltages in precise increments. The 'A' designation indicates the absence of an internal CE pin pull-down resistor and lack of capacitor auto-discharge functionality, distinguishing it from other variants in the family.
