XC6217D312MR-G

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

The XC6217D312MR-G is a fixed-output low dropout regulator from Torex Semiconductor, providing a nominal output voltage of 3.1V with a maximum continuous current of 200mA. It operates within an input voltage range of 1.6V to 6.0V and features Green Operation (GO) technology for optimized power efficiency. The device utilizes a SOT-25-5 surface-mount package and maintains a typical dropout voltage of 80mV at 100mA load. Key electrical characteristics include a standard accuracy of ±2% in high-speed mode, a ripple rejection rate of 70dB at 1kHz, and a standby current of 0.01μA.

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

Verify the specific suffix 'MR-G' corresponds to the SOT-25-5 package configuration. Confirm that the 'D' type designation indicates the presence of the CL discharge resistor and absence of the GO pin. Ensure compliance requirements match the Halogen and Antimony-free status associated with the '-G' suffix.

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

Select this component when a fixed 3.1V output is required with minimal external components. The D-type variant is suitable for applications needing fast output discharge upon shutdown without requiring external logic control for the GO pin. Verify that the operating temperature range of -40°C to +85°C meets system environmental constraints.

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

Does the XC6217D312MR-G have a dedicated GO pin?

No, the D-type designation indicates that this specific package variant does not include a GO pin and always operates in the automatic switching mode.

How is the output discharged when the device is turned off?

The device includes an internal auto-discharge resistor connected between VOUT and VSS when the CE pin is pulled low, rapidly discharging the output capacitor.
