XC6501A351NR-G

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

The XC6501A351NR-G is a high-speed, low-noise CMOS LDO regulator manufactured by Torex Semiconductor. It provides a fixed output voltage of 3.5V 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 load capacitor (CL). Key electrical parameters include a typical dropout voltage of 150mV at 100mA, a supply current of 13μA, and a ripple rejection ratio of 50dB at 1kHz. The part is housed in an SSOT-24 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 that the specific ordering suffix matches the required package type and environmental compliance standards before finalizing procurement. Confirm that the CE pin logic level requirements align with the system control signals, as the A-type series lacks a pull-down resistor on the control pin. Ensure that the input voltage conditions meet the minimum operational thresholds defined in the datasheet specifications.

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

Select this component when a fixed 3.5V output is required with a maximum load of 200mA. The SSOT-24 package is suitable for surface-mount applications where space is limited. Consider the absence of an internal auto-discharge switch for the output capacitor if rapid voltage decay upon shutdown is critical to the application design.

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

This part belongs to the XC6501 series of high-speed LDO regulators. The 'A' designation indicates a regulator type with a High Active CE function, without a CE pull-down resistor, and without an output capacitor discharge feature. It is distinct from B, C, and D types which offer variations in control pin configuration and discharge capabilities.

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

Does the XC6501A351NR-G require an external output capacitor?

No, the device features internal phase compensation that allows it to operate stably without an external load capacitor (CL).

What is the function of the CE pin on the XC6501A series?

The CE pin controls the ON/OFF state of the regulator. A high-level signal turns the device on, while a low-level signal puts it into stand-by mode.
