XC6222C241ER-G

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

The XC6222C241ER-G is a fixed-output low dropout regulator from Torex Semiconductor, providing a nominal output voltage of 2.4 V with a maximum load current of 700 mA. It operates within an input voltage range of 1.7 V to 6.0 V and features a typical dropout voltage of 200 mV at 300 mA. The device maintains high accuracy with a line regulation of 0.01 %/V and offers a power supply rejection ratio of 65 dB at 1 kHz. Quiescent current is limited to 100 μA, while standby current drops below 0.1 μA when the Chip Enable pin is deactivated. It utilizes a USP-6C package and supports an operating ambient temperature range of -40°C to +85°C.

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

• Integrated Chip Enable function allows for active-high control and rapid output discharge via internal auto-discharge switch.
• Built-in over-current protection and thermal shutdown circuits safeguard against excessive load currents and junction temperature limits.
• Reverse current protection prevents backflow from the output to the input, ensuring safety for connected batteries or external supplies.

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

Verify the specific suffix 'C' indicates the Chip Enable type with pull-down resistor but without capacitor discharge functionality. Confirm the 'ER-G' designation corresponds to the USP-6C package format. Ensure compliance with EU RoHS standards and lead-free requirements as specified by the '-G' suffix. Cross-reference the exact output voltage tolerance (+/- 1% for voltages above 2.0 V) against system requirements before finalizing procurement orders.

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

Select this component when a stable 2.4 V rail is required with moderate current demands up to 700 mA. The USP-6C package suits space-constrained designs requiring surface mount technology. Consider the lack of internal capacitor discharge if rapid voltage decay upon shutdown is critical; alternative types like D or H may be necessary in such cases. Verify that the minimum output capacitance requirement aligns with the selected ceramic capacitor's effective value under bias conditions.

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

This part belongs to the XC6222 series of high-speed LDO regulators designed for portable electronic applications. The series emphasizes low noise, high ripple rejection, and compact packaging options including USP-6C, SOT-25, and SOT-89-5. The C-type designation specifically denotes the inclusion of a Chip Enable pin with a pull-down resistor, distinguishing it from non-enable variants.

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

Does the XC6222C241ER-G automatically discharge the output capacitor when disabled?

No, the C-type does not feature an internal auto-discharge switch. Only D, B, F, and H types include this functionality.

What is the minimum recommended output capacitor value for this device?

For an output voltage between 2.1 V and 2.45 V, a minimum ceramic capacitor of 4.7 μF is required for phase compensation.
