S-1701F3327-U5T1G

Overview

The S-1701F3327-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 2.7 V and 3.3 V with a maximum continuous output current of 400 mA per channel. The device features a typical quiescent current of 85 µA and operates within a junction temperature range of -40°C to +85°C. Key electrical specifications include a maximum dropout voltage of 250 mV at 100 mA load, a line regulation of 0.2 %/V, and a load regulation of 40 mV. The unit weight is 30 mg.

Feature Summary

• Integrates dual independent linear regulators for simultaneous power rail generation
• Incorporates built-in voltage detection functionality alongside regulation
• Maintains stable performance with low quiescent current consumption

Applications

• Portable electronic devices requiring multiple regulated supply rails
• Battery-powered systems needing efficient power management
• Embedded circuits utilizing voltage monitoring and regulation

Procurement Notes

Verify the specific suffix U5T1G against official ABLIC documentation to confirm tape-and-reel packaging and lead-free composition. Ensure the ordering part number matches the exact output voltage combination of 2.7 V and 3.3 V. Cross-reference the SOT-23-5 pinout configuration with your PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component when dual fixed outputs are required in a compact SOT-23-5 footprint. The 400 mA current capability supports moderate load applications. Verify that the input voltage exceeds the sum of the highest output voltage and the maximum dropout voltage. Confirm thermal dissipation requirements align with the expected ambient operating conditions and board copper area.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators. The series is characterized by high accuracy and low current consumption. The S-1701F variant specifically denotes the SOT-23-5 package option. This family serves as a power management solution for space-constrained designs requiring integrated regulation and monitoring capabilities.

Replacement Considerations

Direct substitutes within the same series include S-1701F3026-M5T1G and S-1701W2521-U5T1G, provided the output voltage combinations match the design requirements. Verify package compatibility and pinout alignment before substitution.
