XC6501D161GR-G

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

The XC6501D161GR-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 features internal phase compensation, allowing stable operation without an external load capacitor (CL). Key electrical parameters include a typical dropout voltage of 260mV at 100mA, a supply current of 13μA, 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 Feature Summary

• Internal phase compensation enables stable regulation without requiring an external output capacitor.
• Integrated CL auto-discharge function rapidly discharges stored charge in the output capacitor when the CE pin is set to a low level.
• Fold-back current limit circuit provides short-circuit protection and limits output current during overload conditions.

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

Verify that the specific ordering suffix GR-G corresponds to the USP-4 package format as defined in the official datasheet. Confirm that the D series designation matches the requirement for CE High Active logic with both CE pull-down and CL discharge capabilities. Ensure compliance with EU RoHS standards is required for the project specifications.

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

Select this component when a fixed 1.6V output is required with minimal external component count due to the capless design. The D series variant is appropriate if automatic output discharge upon shutdown is necessary. Verify that the input voltage remains above the minimum operating threshold of 1.4V and consider the thermal dissipation limits inherent to the USP-4 package for the expected load current.

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

How does the XC6501D161GR-G achieve stability without an external load capacitor?

Stability is achieved through internal phase compensation circuits integrated within the regulator, eliminating the need for external capacitors typically required for phase correction in other LDO designs.

What is the function of the CL auto-discharge feature in the D series?

When the CE pin is driven low to enter stand-by mode, the CL auto-discharge switch activates, providing a path to discharge the electric charge stored in any connected output capacitor, causing the VOUT pin to quickly return to the VSS level.
