XC6221D1727R-G

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

The XC6221D1727R-G is a fixed-output low dropout regulator from Torex Semiconductor, providing a nominal output voltage of 1.7V with standard accuracy. It operates within an input voltage range of 1.6V to 6.0V and delivers a maximum output current of 200mA. The device features a typical dropout voltage of 125mV at 100mA load and maintains a low supply current of 25μA. It incorporates a CE pin with an internal pull-down resistor and includes a CL auto-discharge function for rapid output discharge. The component is housed in a USPN-4 package.

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

• Integrates a CL auto-discharge switch that rapidly pulls the output voltage to the VSS level when the control signal is deactivated.
• Features an internally pulled-down CE pin that ensures a defined off-state without requiring external components.
• Utilizes laser trimming technology to achieve precise factory-set output voltage increments.

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

Verify the specific ordering suffix against the manufacturer's datasheet to confirm the package type and reel quantity. Ensure the selected variant matches the required output voltage tolerance and thermal dissipation capabilities for the target PCB layout. Confirm RoHS compliance status through official documentation before finalizing procurement specifications.

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

Select this variant when a fixed 1.7V rail is required alongside automatic output discharge functionality. The internal pull-down on the CE pin simplifies logic interfacing by preventing undefined states. Consider the USPN-4 package dimensions for space-constrained designs requiring high-speed transient response and low noise performance.
