XC6503C201MR-G

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

The XC6503C201MR-G is a 500mA high-speed CMOS LDO regulator from Torex Semiconductor. It provides a fixed 2.0V output with ±1% accuracy (±0.02V for lower voltages). Operating within a 1.7V to 6.0V input range, it features internal phase compensation for capacitor-less stability. Key electrical parameters include a typical dropout voltage of 190mV at 300mA, 15μA supply current, and 0.01μA standby current. It includes fold-back current limiting, short-circuit protection, and thermal shutdown.

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

Verify the specific suffix 'MR-G' corresponds to the SOT-25 package and reel quantity as defined in the official datasheet ordering information. Confirm that the 'C' type designation matches the required CE pin pull-down resistor configuration. Ensure compliance with EU RoHS and halogen-free requirements specified by the '-G' suffix before finalizing procurement specifications.

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

Select this component when board space optimization is critical due to its capacitor-less design capability. The C-type variant is suitable for applications requiring a default OFF state when the CE pin is left open, preventing unstable operation. Consider the 15μA active current consumption against the 0.01μA standby requirement for battery-powered portable devices.

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

How does the XC6503C handle an open CE pin?

The XC6503C series includes an internal pull-down resistor on the CE pin. If the pin is left open, the IC defaults to the OFF state, which prevents unstable operation compared to other series types.

Is an output capacitor required for stable operation?

No, the XC6503 series utilizes internal phase compensation, allowing it to operate stably without an external load capacitor (CL), thereby saving board space.
