S-1701R3015-U5T1G

Overview

The S-1701R3015-U5T1G is a dual-output low dropout (LDO) voltage regulator from ABLIC's S-1701 series, housed in an SOT-89-5 surface-mount package. It provides fixed output voltages of 1.5 V and 3.0 V with a maximum continuous output current of 400 mA per channel. The device features a typical quiescent current of 85 µA and supports an input voltage range up to 5.5 V. Operating temperature specifications span from -40 °C to +85 °C, ensuring reliability across standard industrial environments.

Feature Summary

• Integrates two independent positive LDO regulators within a single compact package for space-constrained designs.
• Combines voltage regulation functionality with built-in voltage detection capabilities to monitor supply levels.
• Maintains ultra-low power consumption through a minimal quiescent current draw during active operation.

Applications

• Power management systems requiring dual voltage rails for microcontrollers and peripheral interfaces.
• Battery-operated portable devices where extended standby time necessitates low quiescent current regulators.
• Embedded systems utilizing voltage detection features for supervisory logic and brown-out protection.

Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to confirm pinout compatibility and thermal characteristics. Ensure that the selected variant matches the required output voltage tolerances and package dimensions for your PCB layout. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity before finalizing procurement orders.

Selection Notes

Select this component when a design requires two distinct regulated outputs from a single IC footprint to minimize board space. Consider the 400 mA current capability to ensure it meets the peak load requirements of both downstream circuits. Evaluate the dropout voltage specifications relative to the minimum expected input voltage to maintain stable regulation under varying load conditions.

Part Context

This model belongs to the S-1701 series of combo voltage detectors and regulators designed by ABLIC. The series targets applications needing integrated power management and monitoring functions. The SOT-89-5 package offers a balance between thermal performance and small form factor, suitable for dense electronic assemblies.

Replacement Considerations

Consult ABLIC's official cross-reference lists for verified substitutes. Ensure any replacement maintains identical output voltage pairs, current ratings, and package outline dimensions to guarantee mechanical and electrical compatibility without redesigning the host circuit.
