S-1701N3330-U5T1G

Overview

The S-1701N3330-U5T1G is a dual-output low dropout (LDO) voltage regulator from the ABLIC S-1701 series, housed in an SOT-23-5 surface-mount package. It provides fixed output voltages of 3.3 V and 3.0 V with a maximum output current of 400 mA per channel. The device features a typical quiescent current of 85 µA and supports an input voltage range from 2 V to 6.5 V. Key electrical parameters include a dropout voltage of 140 mV, line regulation of 0.2 %/V, and load regulation of 40 mV. It operates within a temperature range of -40 °C to +85 °C.

Feature Summary

• Integrates two independent linear regulators in a single compact package for space-constrained designs.
• Combines voltage regulation with voltage detection functionality to monitor supply status.
• Maintains stable performance with low quiescent current consumption suitable for battery-powered applications.

Applications

• Power management in portable electronic devices requiring multiple voltage rails
• Voltage monitoring and regulation in embedded systems
• Battery-operated equipment needing efficient power conversion

Procurement Notes

Verify the specific suffix U5T1G against the manufacturer's official documentation to confirm pinout compatibility and tape-and-reel specifications. Ensure that the required output voltages of 3.3 V and 3.0 V align precisely with the target circuit design before procurement. Cross-reference the SOT-23-5 footprint dimensions with PCB layout guidelines to prevent assembly errors.

Selection Notes

Select this component when a dual-output LDO with integrated voltage detection is required in a small form factor. The S-1701N variant specifically offers the SOT-23-5 package, which differs from the SOT-89-5 option available in other series members. Consider the 400 mA output capability and 85 µA quiescent current as primary selection criteria for efficiency and load requirements.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators manufactured by ABLIC Inc. The series is designed to provide both regulated power and voltage supervision in a single IC, reducing component count in power management circuits. The S-1701N designation indicates the specific package type and output configuration within this product family.

Replacement Considerations

Direct substitutes may include other S-1701 series variants with matching output voltages and package types, such as S-1701N3315-M5T1G or S-1701E3026-U5T1G, provided the pinout and electrical characteristics are compatible. Verify package equivalence and thermal performance before substitution.
