S-1701D3024-M5T1G

Overview

The S-1701D3024-M5T1G is a dual-output low dropout (LDO) voltage regulator manufactured by ABLIC. It integrates two fixed positive output channels within a single compact package, designed for applications requiring simultaneous power supply generation and voltage detection. The device features an ultra-low quiesient current of 85 µA to minimize power consumption during standby or active operation. It supports a maximum output current of 400 mA per channel, ensuring adequate drive capability for load circuits. The regulator operates with a wide input voltage range, typically from 2 V to 6.5 V, providing stable regulation across varying supply conditions. Output voltages are fixed at 2.4 V and 3.0 V for the respective channels. The component is housed in a small outline transistor (SOT-23-5) surface-mount package, facilitating space-efficient PCB layouts. It functions reliably within an industrial temperature range of -40°C to +85°C.

Procurement Notes

Verify the specific output voltage configuration matches the design requirements before ordering, as the suffix indicates fixed outputs of 2.4 V and 3.0 V. Confirm that the SOT-23-5 package footprint aligns with the PCB layout specifications. Ensure the thermal management strategy accounts for the power dissipation characteristics under maximum load conditions. Check for RoHS compliance documentation if environmental regulations apply to the final product assembly. Validate that the input voltage range covers the minimum and maximum operating points of the target application circuit.

Selection Notes

Select this component when dual regulated outputs are required alongside voltage detection capabilities in a constrained space. Consider the 85 µA quiescent current as a critical factor for battery-operated applications where standby power loss must be minimized. Evaluate the 400 mA output current capacity against the peak load demands of the connected circuits. Compare the dropout voltage specifications against the minimum input voltage available in the system to ensure proper regulation under all operating conditions. Assess the thermal performance within the SOT-23-5 package for the expected ambient temperature range.

Part Context

The S-1701 series represents ABLIC's lineup of combo voltage detector and regulator ICs, designed to simplify power management designs by combining regulation and monitoring functions. This series targets applications where space savings and reduced component count are prioritized without compromising performance. The S-1701D3024-M5T1G variant specifically offers dual fixed outputs, catering to systems requiring distinct voltage levels for different subsystems. The integration of voltage detection allows for direct monitoring of supply status, enhancing system reliability and fault detection capabilities in embedded environments.

Replacement Considerations

Direct replacements within the S-1701 series should maintain the same output voltage combination and package type. Verify that alternative part numbers offer equivalent quiescent current and output current specifications. Cross-reference pinout configurations to ensure compatibility with existing PCB footprints. Confirm that the thermal and electrical ratings of potential substitutes meet or exceed the original component's requirements for safe operation.
