XC6501B16AGR-G

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

The XC6501B16AGR-G is a high-speed, low-noise CMOS LDO regulator manufactured by Torex Semiconductor. It provides a fixed output voltage of 1.6V with a maximum output current of 200mA. The device operates within an input voltage range of 1.4V to 6.0V and achieves stable regulation without requiring an external load capacitor due to internal phase compensation. Key electrical characteristics include a typical dropout voltage of 260mV at 100mA, a supply current of 13μA, and ripple rejection of 50dB at 1kHz. It features CE control for stand-by mode with less than 0.1μA consumption and includes built-in current limit and short-circuit protection.

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

Verify the specific ordering suffix GR-G confirms the USP-4 package format and reel quantity. Confirm that the B-series designation matches the requirement for the integrated CL discharge feature. Ensure the CE pin logic level aligns with the system's control signals, as this variant is CE High Active. Cross-reference the exact part number against the manufacturer's latest datasheet to confirm RoHS compliance status.

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

Select this component when a fixed 1.6V rail is required from inputs between 1.4V and 6.0V. The B-series type is necessary if automatic output capacitor discharge upon shutdown is needed. Consider the USP-4 package constraints regarding power dissipation and thermal management. Verify that the 200mA current capability meets the peak load requirements of the target application circuit.

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

Does the XC6501B16AGR-G require an external output capacitor?

No, the device utilizes internal phase compensation to ensure stable operation without an external load capacitor.

What is the function of the CL discharge feature in this model?

When the CE pin is set to Low, an internal N-channel transistor discharges the electric charge stored on any connected output capacitor, allowing the VOUT pin to quickly return to the VSS level.
