XC6604B141MR-G

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

The XC6604B141MR-G is a low voltage input, high speed LDO regulator manufactured by Torex Semiconductor. It operates with an input voltage range of 0.5V to 3.0V and provides a fixed output voltage of 1.4V. The device supports a maximum output current of 1A with adjustable current limiting capabilities via the ILIM pin. It features ±20mV output voltage accuracy for voltages at or above 1.2V. The regulator includes built-in protection circuits such as thermal shutdown, under-voltage lockout, and foldback current limit. It utilizes a SOT-26W package and is designed for applications requiring efficient power management in low voltage environments.

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

• Adjustable current limit functionality allows customization of protection thresholds using 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.
• Built-in CL auto-discharge circuit rapidly discharges electric charge from the output capacitor upon shutdown to prevent malfunction.
• Compatible with ceramic capacitors for output stabilization, simplifying design requirements while maintaining phase compensation stability.

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

Verify the specific ordering suffix MR-G corresponds to the SOT-26W package configuration required for your PCB layout. Confirm that the Type B designation indicates the absence of a soft-start function, which may impact inrush current behavior during startup compared to Type A variants. Ensure compatibility with your system's bias voltage requirements before finalizing procurement.

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

Select this component when a fixed 1.4V output is required within the 0.5V to 3.0V input range. Consider the Type B variant if soft-start functionality is not needed and faster response times are acceptable. Evaluate the need for adjustable current limiting; if fixed limits suffice, standard configurations apply. Verify thermal dissipation capabilities based on the expected load current and ambient temperature conditions.

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