XC6604B111ER-G

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

The XC6604B111ER-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 1.1V. The device supports a maximum output current of 1A with adjustable current limiting capabilities via the ILIM pin. Key electrical characteristics include ±20mV output voltage accuracy for voltages ≥1.2V (±15mV for <1.2V), typical ripple rejection of 75dB at 1kHz, and ultra-low standby current of 0.01μA. It features built-in thermal shutdown, under-voltage lockout, soft-start, and CE pull-down functions.

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 foldback circuit reduces output voltage and current during short-circuit conditions to enhance system safety.
• CE pull-down function maintains the IC in stand-by mode when the control pin is left open, preventing unintended operation.

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

Verify the specific package type USP-6C and ordering suffix ER-G against the manufacturer's latest datasheet to ensure compatibility with PCB layout requirements. Confirm that the laser-trimmed output voltage matches the design specification of 1.1V. Check for RoHS compliance status as indicated by the -G suffix before finalizing procurement orders.

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

Select this component for applications requiring stable regulation from very low input voltages down to 0.5V. Ensure the bias voltage VBIAS is maintained within the 2.5V to 6.0V range for optimal performance. Consider the thermal dissipation limits in the USP-6C package if operating near maximum current loads or elevated ambient temperatures.
