S-1701S1515-M5T1G

Overview

The S-1701S1515-M5T1G is a low dropout voltage regulator manufactured by ABLIC, belonging to the S-1701 series. It integrates a fixed linear regulator with a built-in voltage detector within a single compact package. The device features a quiescent current of 85 µA and supports an output current of 400 mA. It provides two fixed output voltages: 1.5 V for the regulator channel and 1.5 V for the voltage detection threshold. The component operates within an input voltage range of 2 V to 6.5 V and maintains functionality across a temperature range of -40°C to +85°C.

Feature Summary

• Combines a low dropout linear regulator and a voltage detector in one unit
• Provides high output current capability of 400 mA
• Features ultra-low quiescent current consumption of 85 µA
• Utilizes a compact SOT-23-5 surface-mount package

Applications

• Battery-powered portable electronic devices requiring power management
• Embedded systems needing integrated voltage supervision
• Microcontroller power supply circuits with reset monitoring
• IoT sensor nodes with strict power budget constraints

Procurement Notes

Verify the specific output voltage configuration and detection threshold against the official datasheet before procurement. Confirm that the SOT-23-5 package footprint matches the design layout. Ensure the operating temperature range meets the environmental requirements of the target application. Check for any recent product change notifications or obsolescence notices from ABLIC to ensure long-term availability.

Selection Notes

Select this component when space efficiency and combined regulation-detection functionality are required. The 400 mA output current suits moderate load applications, while the 85 µA IQ aids battery life extension. Consider the 1.5 V fixed outputs for logic level compatibility. Evaluate thermal dissipation capabilities given the small package size under maximum load conditions.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators from ABLIC. These components are designed to replace separate regulator and supervisor ICs, reducing board space and component count. The series is characterized by low current consumption and robust performance in automotive and industrial environments.

Replacement Considerations

Direct replacements include other S-1701 series variants with matching output voltages and package types, such as S-1701R1515-M5T1G or S-1701D1515-M5T1G, provided electrical parameters align. Cross-series substitution requires careful verification of pinout compatibility and thermal characteristics.
