XC6501C441NR-G

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

The XC6501C441NR-G is a high-speed, low-noise CMOS LDO regulator manufactured by Torex Semiconductor. It provides a fixed output voltage of 4.4V with a maximum output current of 200mA. The device operates within an input voltage range of 1.4V to 6.0V and features internal phase compensation, allowing for stable operation without an external output capacitor (CL). Key electrical parameters include a typical dropout voltage of 150mV at 100mA, a supply current of 13μA, and a stand-by current of less than 0.1μA when the CE pin is asserted low. It includes built-in protection circuits such as current limit and short-circuit protection.

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

• Internal phase compensation enables stable regulation without requiring an external output capacitor.
• CE pin control allows switching between active mode and ultra-low power stand-by mode.
• Built-in fold-back current limiter and short-circuit protection safeguard the output stage.
• Low noise and high ripple rejection characteristics suitable for sensitive analog loads.

• Smart phones and mobile phones
• Portable game consoles
• Wireless communication modules
• Digital-TV tuners

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

Verify the package type corresponds to SSOT-24 for the NR-G suffix. Confirm the output voltage tolerance matches the application requirements, noting that standard increments are 0.1V or 0.05V depending on the specific series variant. Ensure the design accounts for the absence of an output capacitor while maintaining adequate input capacitance for stability under transient load conditions.

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

Select this component for applications requiring compact designs due to the elimination of output capacitors. Consider the 13μA supply current for battery-powered devices where standby consumption is critical. Verify that the input voltage remains above the minimum operating threshold plus the dropout voltage across the full load and temperature range. The C-type designation indicates a pull-down resistor on the CE pin, which prevents undefined states if the control pin is left floating.

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

This part belongs to the XC6501 series of 200mA High Speed LDO Regulators. The series is characterized by its ability to operate stably without an output capacitor, a feature achieved through internal phase compensation rather than external components. The 'C' in the model number specifies the regulator type with a CE pin that is high-active and includes an internal pull-down resistor. The '441' indicates the nominal output voltage setting.
