S-1701D3326-M5T1G

Overview

The S-1701D3326-M5T1G is a dual-output low-dropout (LDO) voltage regulator from the ABLIC S-1701 series, housed in an SOT-23-5 surface-mount package. It provides fixed output voltages of 2.6 V and 3.3 V with a maximum continuous output current of 400 mA per channel. The device operates within an input voltage range of 2 V to 6.5 V and features a typical quiescent current of 85 µA. It maintains a dropout voltage of approximately 140 mV at rated load and ensures voltage regulation accuracy of ±1%. The component supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates two independent LDO regulators with integrated voltage detector functionality for system monitoring.
• Delivers high output current capability of 400 mA while maintaining ultra-low standby power consumption.
• Provides precise voltage regulation with tight tolerance specifications suitable for sensitive digital logic.

Applications

• Powering dual-voltage domains in portable electronic devices
• Supplying stable rails for microcontrollers and memory modules
• Battery-operated equipment requiring extended operational life

Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to confirm pinout compatibility and thermal characteristics. Ensure that the selected variant matches the required output voltage combination and package type for your PCB layout. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a design requires two distinct regulated voltages from a single IC footprint to save board space. Consider the 400 mA current rating to ensure it meets the peak load requirements of both output channels simultaneously. Evaluate the input voltage range to guarantee sufficient headroom for the lowest expected supply voltage while maintaining regulation under all operating conditions.

Part Context

This device belongs to the S-1701 series of combo voltage detectors and regulators designed by ABLIC Inc. The series is characterized by its compact SOT-23-5 packaging and low quiescent current, making it ideal for space-constrained applications. It serves as a power management solution for systems needing reliable voltage regulation combined with simple voltage monitoring capabilities.

Replacement Considerations

Check for direct substitutes within the S-1701 family that offer different fixed output combinations but share the same SOT-23-5 package and electrical interface. Verify pin-to-pin compatibility if swapping between variants with different output voltage pairs to avoid redesigning the printed circuit board.
