S-1701Q3315-M5T1G

Overview

The S-1701Q3315-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 3.3 V and 1.5 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 voltage regulation accuracy of 1% and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates two independent LDO regulators with combined voltage detection capabilities for system monitoring.
• Maintains stable operation with ultra-low standby current consumption suitable for battery-powered applications.
• Delivers high output current capability while maintaining tight voltage regulation accuracy across load variations.

Applications

• Portable electronic devices requiring multiple regulated voltage rails from a single source
• Battery-operated systems needing efficient power management and extended runtime
• Embedded controllers utilizing integrated voltage supervision for reliable startup sequences

Procurement Notes

Verify the specific suffix M5T1G corresponds to the required tape-and-reel packaging configuration before ordering. Confirm that the dual output combination of 3.3 V and 1.5 V matches the target circuit design requirements. Ensure compatibility with the SOT-23-5 footprint during PCB layout verification. Check for any recent product change notifications regarding manufacturing updates or material substitutions.

Selection Notes

Select this component when a compact dual-rail solution is needed alongside voltage monitoring functions. The S-1701 series offers a balance of low quiescent current and moderate output current capacity. Consider the thermal performance in the SOT-23-5 package under maximum load conditions. Verify that the input voltage range adequately covers the supply source variations expected in the application environment.

Part Context

This part belongs to the ABLIC S-1701 family of CMOS LDO regulators designed for portable equipment. The series emphasizes low power consumption and small form factors. These regulators are commonly used in mobile phones, digital cameras, and other handheld devices where space and efficiency are critical constraints.

Replacement Considerations

Direct substitutes include other S-1701 variants with different output voltage combinations such as S-1701N3315-M5T1G or S-1701R3315-M5T1G. Cross-reference pinouts and electrical characteristics to ensure functional equivalence without redesigning the surrounding circuitry.
