S-1701V3327-M5T1G

Overview

The S-1701V3327-M5T1G is a dual-output low-dropout (LDO) voltage regulator and voltage detector integrated circuit manufactured by ABLIC. It provides fixed output voltages of 2.7 V and 3.3 V with a maximum output current of 400 mA. The device features a low quiescent current of 85 µA and operates within an input voltage range of 2 V to 6.5 V. It utilizes an SOT-23-5 surface-mount package and supports a junction temperature range from -40°C to +85°C. The regulator offers a typical dropout voltage of 140 mV and maintains a voltage regulation accuracy of 1%.

Feature Summary

• Integrates dual fixed-voltage LDO regulators with a combined voltage detection function for system monitoring.
• Delivers high output current capability of 400 mA while maintaining ultra-low standby power consumption.
• Ensures stable performance across wide input voltage variations with minimal dropout voltage characteristics.

Applications

• Portable electronic devices requiring efficient power management and battery life extension.
• Embedded systems needing simultaneous regulated supply rails and voltage supervision.
• Industrial control modules operating in extended temperature environments.

Procurement Notes

Verify the specific output voltage combination of 2.7 V and 3.3 V against design requirements, as the S-1701 series contains numerous variants with different voltage pairs. Confirm the SOT-23-5 package footprint matches the PCB layout. Ensure the thermal dissipation capabilities are sufficient for the intended load conditions within the specified operating temperature range.

Selection Notes

Select this component when a single IC solution is required to provide two distinct regulated voltages alongside a voltage detection feature. It is suitable for designs prioritizing low quiescent current to maximize battery life in portable applications. Consider the 400 mA output current limit and the 140 mV dropout voltage to ensure adequate headroom for the specific load requirements and input voltage constraints.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators from ABLIC. The series is designed to replace separate regulator and supervisor components, reducing board space and component count. It is commonly used in consumer electronics and industrial applications where power efficiency and system reliability are critical.

Replacement Considerations

Compatible substitutes include other S-1701 series parts with identical 2.7 V and 3.3 V outputs, such as S-1701N3327 or S-1701R3327, provided the package type matches. Verify that any replacement maintains the same 400 mA output current and 85 µA quiescent current specifications.
