Procurement Notes

Verify the specific output voltage combination of 2.6 V and 3.3 V against system requirements before procurement. Confirm that the SOT-23-5 package dimensions align with the PCB layout constraints. Ensure the operating temperature range meets the environmental conditions of the final application. Cross-reference the manufacturer datasheet for detailed electrical characteristics and thermal performance data.

Selection Notes

Select this component when a single IC solution is needed to provide two distinct regulated voltages alongside voltage monitoring. The low quiescent current makes it suitable for battery-operated applications where power efficiency is critical. Consider the 400 mA output current capacity to ensure it meets the peak load demands of the connected circuits. Verify compatibility with the available input voltage range of up to 6.5 V.

Part Context

This part belongs to the ABLIC S-1701 series of combo voltage detectors and regulators. The series is designed to offer high integration by combining LDO functionality with voltage detection capabilities. These components are typically used in applications requiring space-saving solutions and efficient power management in portable electronics.

Replacement Considerations

Check for other S-1701 series variants with different output voltage combinations if the 2.6 V/3.3 V pair does not match the design needs. Verify pin-to-pin compatibility with alternative dual-output LDOs from other manufacturers if supply issues arise.
