XC6501A21ANR-G

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

The XC6501A21ANR-G is a high-speed, low-noise CMOS LDO regulator from Torex Semiconductor. It provides a fixed output voltage of 2.1V 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 stable operation without an external load capacitor. Key electrical parameters include a typical dropout voltage of 190mV at 100mA, a supply current of 13μA, and a ripple rejection ratio of 50dB at 1kHz. It includes protection circuits for current limiting and short-circuit conditions.

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

• Internal phase compensation enables stable regulation without requiring an external output capacitor.
• Low power consumption with a standby current reduced to less than 0.1μA via the CE pin control function.
• Integrated fold-back current limit circuit provides short-circuit protection for the output pin.

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

• Smart phones and mobile phones
• Portable game devices
• Wireless and camera modules
• Bluetooth modules
• Digital-TV tuners

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

Verify the specific package type SSOT-24 against the required PCB footprint before ordering. Confirm that the CE pin logic level (High Active) matches the system control signals. Ensure the input voltage remains within the 1.4V to 6.0V operational range to maintain specified performance characteristics.

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

Select this component when a fixed 2.1V rail is needed with minimal external components due to the capless design. Consider the 190mV dropout voltage relative to the minimum input voltage available in the application. The A-type designation indicates no auto-discharge feature, which may influence shutdown behavior compared to B or D series variants.

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 load capacitors, distinguishing it from traditional LDOs requiring external compensation. The 'A' suffix denotes a specific configuration with CE High Active functionality and no CL discharge switch.
