S-1701C3330-M5T1G

Overview

The S-1701C3330-M5T1G is a dual-output low dropout (LDO) voltage regulator and voltage detector combo IC manufactured by ABLIC. It provides fixed output voltages of 3.0 V and 3.3 V with a maximum output current of 400 mA per channel. The device features a low quiescent current of 85 µA, ensuring efficient power management in battery-operated applications. It operates within an input voltage range of 2 V to 6.5 V and maintains a typical dropout voltage of 140 mV at 100 mA. The unit is housed in a compact SOT-23-5 package and supports operation from -40°C to +85°C.

Feature Summary

• Integrates dual LDO regulators with a built-in voltage detector for combined power management and monitoring functions.
• Delivers high output current capability of 400 mA while maintaining ultra-low standby current consumption.
• Provides precise voltage regulation with tight accuracy specifications suitable for sensitive digital logic circuits.

Applications

• Portable electronic devices requiring efficient multi-rail power distribution
• Battery-powered systems needing extended operational life through low quiescent current
• Embedded controllers requiring integrated voltage supervision for system stability

Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure correct pinout and electrical characteristics. Confirm RoHS compliance status and packaging details directly with authorized distributors. Cross-reference the part number with the latest product change notifications to avoid obsolete variants during procurement.

Selection Notes
