S-1701R3315-M5T1G

Overview

The S-1701R3315-M5T1G is a dual-output low dropout (LDO) voltage regulator from the ABLIC S-1701 series, integrating a voltage detector. It provides fixed output voltages of 1.5 V and 3.3 V with a maximum output current of 400 mA. The device operates within an input voltage range of 2 V to 6.5 V and features a typical quiescent current of 85 µA. Packaged in an SOT-23-5 surface-mount case, it supports operation temperatures from -40°C to +85°C.

Feature Summary

• Integrates dual LDO regulators with a combined voltage detection function for space-constrained designs.
• Maintains stable regulation with low quiescent current consumption suitable for battery-powered applications.
• Delivers high output current capability while maintaining low dropout voltage characteristics.

Applications

• Portable electronic devices requiring multiple regulated supply rails
• Battery-operated systems needing efficient power management
• Embedded circuits utilizing integrated voltage monitoring

Procurement Notes

Verify the specific output voltage combination matches the design requirement, as the suffix indicates 1.5 V and 3.3 V outputs. Confirm the SOT-23-5 package compatibility with the PCB footprint. Ensure the operating temperature range meets the environmental specifications of the final application. Check for any recent product change notifications that might affect pinout or electrical parameters.

Selection Notes

Select this component when a single IC solution is needed for both power regulation and voltage supervision. Compare the dropout voltage requirements against the minimum input voltage available in the system. Consider the thermal performance in the SOT-23-5 package if high load currents are sustained. Verify that the fixed output voltages align precisely with the target logic levels.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators by ABLIC. These devices are designed to reduce component count in portable electronics by combining linear regulation with voltage monitoring functions. The series offers various fixed output combinations to suit different digital logic families.

Replacement Considerations

Direct substitutes include other S-1701 variants with identical SOT-23-5 packaging and similar electrical characteristics, such as S-1701R1815-M5T1G or S-1701Q1515-M5T1G, provided the output voltage differences are acceptable for the circuit design.
