S-1701P3315-M5T1G

Overview

The S-1701P3315-M5T1G is a low-dropout (LDO) voltage regulator manufactured by ABLIC Inc. It features two fixed output voltages: 1.5 V and 3.3 V. The device supports a maximum output current of 400 mA with a typical quiescent current of 85 µA. It operates within an input voltage range of 2.0 V to 6.5 V and maintains a maximum dropout voltage of 140 mV at full load. The component is housed in a compact SOT-89-5 surface-mount package and is rated for operation between -40°C and +85°C.

Feature Summary

• Integrates dual fixed voltage outputs (1.5 V and 3.3 V) in a single package
• Provides high output current capability of 400 mA with low quiescent current consumption
• Features low dropout voltage characteristics for efficient power management
• Includes built-in voltage detection functionality for system monitoring

Applications

• Battery-powered portable electronic devices requiring multiple voltage rails
• Mobile communication equipment needing stable power supply under varying loads
• Embedded systems utilizing voltage detectors for power sequence control

Procurement Notes

Verify the specific suffix M5T1G confirms the SOT-23-5 or SOT-89-5 package variant as listed in official ABLIC documentation, noting potential discrepancies in distributor listings. Ensure the order quantity aligns with manufacturer reel specifications. Confirm RoHS compliance status directly from the latest datasheet revision before procurement.

Selection Notes

Select this component when dual fixed outputs are required without external resistors. The 400 mA output current suits moderate load applications. Verify that the 1.5 V and 3.3 V levels match system requirements. The wide input range accommodates single-cell battery discharge profiles. Check thermal dissipation capabilities in the SOT-89-5 package for the intended ambient temperature conditions.

Part Context

This part belongs to the S-1701 series of combo voltage detector/regulator ICs from ABLIC. The series is designed for low-power applications integrating regulation and monitoring functions. Similar parts in the family vary by output voltage combinations and package types, such as SOT-23-5 or SOT-89-5, while maintaining consistent electrical performance characteristics.

Replacement Considerations

Direct substitutes include other S-1701 series variants with matching 1.5 V/3.3 V outputs and compatible packages. Verify pin compatibility and electrical parameters against original datasheets before substitution.
