XC6223T301MR-G

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

The XC6223T301MR-G is a high-speed low-dropout voltage regulator manufactured by Torex Semiconductor. It provides a fixed output voltage of 3.0 V with an accuracy of ±1%. The device supports a maximum output current of 300 mA and operates within an input voltage range of 1.6 V to 5.5 V. Key electrical characteristics include a typical dropout voltage of 200 mV at full load, a supply current of 100 μA, and a standby current of 0.01 μA. It features a power supply rejection ratio of 80 dB at 1 kHz. The component is housed in a SOT-25-5 package and is designed for operation across an ambient temperature range of -40°C to +105°C.

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

Verify that the specific part number matches the required design specifications before procurement. Confirm the package type is SOT-25-5 and the output voltage is exactly 3.0 V. Ensure the operating environment stays within the specified temperature range of -40°C to +105°C. Check for RoHS compliance requirements if applicable to your manufacturing process. Validate that the input voltage does not exceed the maximum rating of 5.5 V during normal operation.

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

Select this component when a fixed 3.0 V rail is needed with minimal quiescent current consumption. The integrated inrush current protection makes it suitable for systems sensitive to startup surges. The auto-discharge feature is advantageous for applications requiring rapid power-down states. Ensure the application can accommodate the SOT-25-5 footprint and that the thermal dissipation capabilities are sufficient for the expected load conditions.

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

How does the XC6223T301MR-G handle startup inrush current?

It utilizes a built-in inrush current prevention circuit that limits the initial surge current to approximately 150 mA during startup, protecting downstream components from sudden current spikes.

What happens to the output voltage when the CE pin is set to low?

When the CE pin is low, the device enters standby mode and activates an internal auto-discharge switch. This rapidly discharges the output capacitor, pulling the VOUT pin quickly back to the VSS (ground) level.
