XC6501A12AGR-G

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

The XC6501A12AGR-G is a high-speed, low-noise CMOS LDO regulator manufactured by Torex Semiconductor. It provides a fixed output voltage of 1.2V 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 (CL). Key electrical parameters include a typical dropout voltage of 440mV at 100mA, a supply current of 11μA, and a ripple rejection ratio of 50dB at 1kHz. The part is housed in a USP-4 package and supports an operating ambient temperature range from -40°C to +85°C.

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

Verify the specific ordering suffix GR-G corresponds to the USP-4 package configuration as defined in the manufacturer's documentation. Confirm that the A-type designation indicates the absence of a CE pull-down resistor and CL discharge function. Ensure compatibility with the required input voltage range and thermal dissipation constraints for the target PCB layout before finalizing procurement.

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

Select this component when a fixed 1.2V output is required with a maximum load of 200mA. The USP-4 package offers a compact footprint suitable for space-constrained designs. Consider the 440mV dropout voltage relative to the minimum available input voltage to ensure proper regulation under all operating conditions. Verify that the lack of auto-discharge functionality aligns with system shutdown requirements.

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

This part belongs to the XC6501 series of high-speed LDO regulators from Torex Semiconductor. The series is characterized by its ability to operate stably without external output capacitors due to internal phase compensation. The 'A' variant specifically denotes a control enable pin that is active-high without a pull-down resistor and lacks the internal auto-discharge switch found in other variants like B or D.

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

Does the XC6501A12AGR-G require an external output capacitor?

No, the device utilizes internal phase compensation to maintain stability without an external load capacitor (CL).

What is the function of the CE pin on this specific model?

The CE pin controls the ON/OFF state; a high signal turns the regulator on, while a low signal puts it into stand-by mode. This model does not have an internal pull-down resistor on the CE pin.
