XC6220A201ER-G

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

The XC6220A201ER-G is a CMOS low dropout voltage regulator manufactured by Torex Semiconductor. It provides a fixed output voltage of 2.0V with a maximum continuous output current of 700mA for this specific voltage range. The device operates within an input voltage range of 1.6V to 6.0V and features Green Operation technology, which automatically switches between high-speed and power-save modes to minimize supply current. It utilizes the USP-6C surface-mount package.

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

Verify that the XC6220A series designation confirms the absence of a CE pull-down resistor and CL auto-discharge feature, as these are distinct from B, C, and D types. Ensure the ER-G suffix matches the required USP-6C packaging and RoHS compliance specifications for your manufacturing process.

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

Select this component when a fixed 2.0V output is required with a maximum load current of 700mA. Note that the A-series lacks internal pull-down resistors and output discharge transistors found in other variants. Verify that the application does not require the CE pin to be left open during standby, as this results in an undefined state for the A-series.

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

This part belongs to the XC6220 series of 1A LDO regulators. While the series supports up to 1A output for voltages above 1.2V, the XC6220A201ER-G is rated for 700mA due to its 2.0V output classification. It shares the core architecture of voltage reference, error amplifier, and driver transistor common to the family.

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

How does the Green Operation function affect the XC6220A201ER-G?

It automatically switches the IC between high-speed mode and power-save mode depending on the output current level, significantly reducing supply current during light-load conditions.

What is the status of the CE pin if left open on this specific model?

For the XC6220A series, leaving the CE pin open results in an undefined state where the output may become unstable; it must be connected to a valid voltage level.
