XC6217B30AGR-G

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

The XC6217B30AGR-G is a fixed-output low dropout regulator from Torex Semiconductor, providing a nominal output voltage of 3.0V with a maximum load current of 200mA. It operates within an input voltage range of 1.6V to 6.0V and features a typical dropout voltage of 80mV at 100mA. The device incorporates Green Operation (GO) technology for automatic switching between high-speed and power-save modes, achieving a quiescent current as low as 4.5μA in power-save mode. It includes built-in short-circuit protection, thermal shutdown, and a capacitor discharge function.

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

• Green Operation (GO) function enables automatic switching between high-speed operation and low-power consumption modes based on load current levels.
• Integrated capacitor discharge circuit rapidly discharges the output capacitor when the control pin is deactivated.

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

Verify the specific package type USP-4D and the B-type designation which indicates the presence of the capacitor discharge resistor. Confirm that the GO pin logic requirements match the system design, as leaving it open results in undefined operation. Ensure compliance with RoHS standards by checking the -G suffix documentation.

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

Select this component for applications requiring precise 3.0V regulation with minimal standby power consumption. The B-type variant is suitable where rapid output discharge upon shutdown is required. Consider the 80mV dropout voltage relative to the minimum input supply to ensure stable regulation under all load conditions.

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

How does the Green Operation function affect performance?

The GO function automatically switches between High-Speed (HS) mode for heavy loads and Power-Save (PS) mode for light loads, optimizing efficiency by reducing supply current to 4.5μA in PS mode while maintaining high-speed response when needed.

What is the purpose of the capacitor discharge resistor in the B-type?

The internal switch connected between VOUT and VSS allows the output capacitor to discharge quickly via the auto-discharge resistance when the CE pin is set to low, ensuring the output voltage returns to the VSS level rapidly.
