XC6604A161MR-G

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

The XC6604A161MR-G is a low voltage input, high speed LDO regulator from Torex Semiconductor. It operates with an input voltage range of 0.5V to 3.0V and provides a fixed output voltage of 1.6V. The device supports a maximum output current of 1A with adjustable current limiting capabilities via the ILIM pin. Key electrical characteristics include a typical ripple rejection ratio of 75dB at 1kHz and a standby current as low as 0.01μA. It features built-in protections such as thermal shutdown, under-voltage lockout, and foldback current limit.

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

• Adjustable current limit functionality allows customization of protection thresholds via an external resistor connected to the ILIM pin.
• Integrated CE pull-down function ensures the device enters stand-by mode when the control pin is left open, reducing power consumption.
• Fast discharge capability for the output capacitor during shutdown prevents malfunction by quickly pulling the output to ground level.

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

Verify the specific package type SOT-26W and the Type A designation which includes soft-start functionality. Confirm that the ordering suffix MR-G indicates halogen and antimony-free compliance. Ensure the selected component matches the required output voltage accuracy specifications for your application design.

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

Select this variant for applications requiring a stable 1.6V supply from low input voltages. Consider the Type A configuration if soft-start behavior is necessary to manage inrush currents during startup. Evaluate the thermal dissipation requirements based on the PCB mounting conditions and ambient temperature limits.

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

This component belongs to the XC6604 series of low dropout regulators designed for high efficiency operation. The series utilizes N-ch driver transistors to achieve ultra-low on-resistance. The Type A designation specifically denotes the inclusion of a soft-start circuit, distinguishing it from Type B variants which lack this feature.
