S-1701P1815-M5T1G

Overview

The S-1701P1815-M5T1G is a low-dropout (LDO) voltage regulator manufactured by ABLIC Inc., belonging to the S-1701 series. It integrates a voltage detector function within a single package, classified as a COMBO VOLT DET/REG device. The component operates with an ultra-low quiescent current of 85 µA and supports a maximum output current of 400 mA. It features two fixed output voltages: 1.5 V and 1.8 V. The device utilizes an SOT-23-5 surface-mount package and is designed for positive polarity applications. It functions reliably within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates LDO regulation and voltage detection in a single compact package
• Ultra-low quiescent current consumption for extended battery life
• Dual fixed output voltage configuration for multi-rail systems
• High output current capability suitable for portable electronics

Applications

• Battery-powered portable electronic devices
• Mobile communication equipment
• Consumer electronics requiring efficient power management
• Embedded systems with strict size constraints

Procurement Notes

Verify the specific output voltage combination (1.5V/1.8V) against design requirements before ordering. Confirm the SOT-23-5 package footprint compatibility with PCB layout. Ensure the operating temperature range meets environmental specifications. Check for RoHS compliance documentation if required by regulatory standards. Validate input voltage limits to prevent damage during operation.

Selection Notes

Select this component when dual voltage rails are needed from a single regulator IC to save board space. The 85 µA quiescent current makes it suitable for always-on applications where standby power is critical. The 400 mA output current supports moderate load demands typical in handheld devices. Consider the SOT-23-5 package size for tight spatial constraints compared to larger packages.

Part Context

This part belongs to the ABLIC S-1701 series, which combines LDO regulators with voltage detectors. The series is designed for low-power applications requiring high efficiency and small form factors. Similar parts in the series vary by output voltage combinations and specific detector thresholds, but share the same core architecture and package style.

Replacement Considerations

Direct substitutes may include other S-1701 series variants with different voltage outputs if electrical parameters match. Verify pin-to-pin compatibility with alternative LDOs offering similar current and quiescent current specs. Ensure replacement components support the same dual-output configuration or adjust circuit design accordingly.
