S-1701V5042-M5T1G

Overview

The S-1701V5042-M5T1G is a dual-output low dropout (LDO) voltage regulator manufactured by ABLIC. It provides fixed output voltages of 4.2 V and 5 V with a maximum 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 utilizes an SOT-23-5 surface-mount package and supports an operating temperature range from -40 °C to +85 °C. Key electrical characteristics include a line regulation of 0.2 %/V, load regulation of 40 mV, and a power dissipation rating of 420 mW.

Feature Summary

• Integrates two independent fixed-voltage linear regulators in a single compact package
• Combines voltage regulation functionality with built-in voltage detection circuits
• Maintains stable performance with ultra-low standby current consumption

Applications

• Battery-powered portable electronic devices requiring multiple supply rails
• Automotive infotainment and instrument cluster systems
• Industrial control modules needing reliable voltage monitoring and regulation

Procurement Notes

Verify the specific output voltage combination against the official datasheet before ordering, as suffix codes determine exact parameters. Confirm package type and thermal requirements for your PCB layout. Ensure compliance with RoHS directives if required by your manufacturing standards. Cross-reference the manufacturer part number with distributor listings to confirm availability and lead times.

Selection Notes

Select this component when a design requires two distinct regulated voltages alongside voltage supervision in a space-constrained environment. The SOT-23-5 package offers a balance between thermal performance and footprint size. Consider the 400 mA output capability and low dropout characteristics relative to your input voltage headroom and load requirements.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators from ABLIC. The series is designed for applications requiring both power management and system monitoring functions. It is commonly used in automotive and industrial sectors where reliability and compact form factors are critical for embedded electronics.

Replacement Considerations

Direct replacements must match the dual-output configuration, SOT-23-5 package, and similar electrical specifications. Verify that any substitute component supports the same voltage detection thresholds and output current capabilities to ensure circuit compatibility.
