S-1701C2522-U5T1G

Overview

The S-1701C2522-U5T1G is a dual-output low dropout voltage regulator from the ABLIC S-1701 series, housed in an SOT-89-5 surface-mount package. It provides fixed output voltages of 2.2 V and 2.5 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 line regulation of 0.2%/V, load regulation of 40 mV, and a power dissipation rating of 1 W.

Feature Summary

• Dual independent fixed voltage outputs for simultaneous supply requirements
• Ultra-low quiescent current consumption for battery efficiency
• Integrated voltage detection circuitry for system monitoring

Applications

• Portable electronic devices requiring multiple stable voltage rails
• Battery-powered consumer electronics
• Embedded systems with strict power budget constraints

Procurement Notes

Verify the specific output voltage combination (2.2 V and 2.5 V) against schematic requirements before ordering. Confirm that the SOT-89-5 footprint matches the PCB layout. Ensure the thermal design accommodates the 1 W power dissipation limit under expected operating conditions. Check for RoHS compliance documentation if required by regional regulations.

Selection Notes

Select this component when two distinct regulated voltages are needed from a single package to save board space. The 400 mA output current supports moderate load demands. Consider the 85 µA quiescent current as a critical factor for standby power optimization. Verify input voltage headroom against the dropout characteristics for the selected loads.

Part Context

This part belongs to the S-1701 series of combo voltage detector/regulator ICs. These devices integrate linear regulators with voltage detection functions, offering a compact solution for power management. The series is characterized by low current consumption and high reliability, suitable for applications where space and power efficiency are prioritized over high-current delivery.

Replacement Considerations

Direct substitutes within the same series include S-1701E3026-U5T1G (3.0 V/2.6 V), S-1701W2521-U5T1G (2.5 V/2.1 V), and S-1701R1815-U5T1G (1.8 V/1.5 V). All share identical pinouts, packages, and general electrical characteristics, differing only in the fixed output voltage pairs.
