S-1701R5015-U5T1G

Overview

The S-1701R5015-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 5.0 V with a maximum output current of 400 mA per channel. The device features a typical quiescent current of 85 µA and a maximum dropout voltage of 340 mV at full load. It operates within a temperature range of -40°C to +85°C and includes built-in overcurrent protection and thermal shutdown circuits for reliable operation.

Feature Summary

• Integrates two independent positive voltage regulators with fixed output settings in a single compact package.
• Combines low power consumption with high output current capability suitable for battery-powered applications.
• Includes internal protection mechanisms against excessive load current and overheating conditions.

Applications

• Power management in portable electronic devices requiring multiple stable voltage rails.
• Voltage regulation for microcontrollers and peripheral circuits in embedded systems.
• Battery-operated equipment needing efficient step-down conversion with minimal standby current.

Procurement Notes

Verify the specific suffix U5T1G corresponds to the required tape-and-reel packaging configuration. Confirm that the SOT-89-5 footprint matches your PCB layout constraints. Ensure input voltage levels remain within safe operating limits relative to the 5.0 V output to prevent excessive power dissipation during procurement validation.

Selection Notes

Select this component when dual isolated outputs are necessary without additional external switching components. Compare dropout characteristics against other LDOs if load transients are significant. Consider thermal performance in enclosed designs due to the SOT-89-5 package size. Verify compatibility with ceramic capacitors as recommended by manufacturer guidelines for stability.

Part Context

Part of the S-1701 series focusing on combo voltage detection and regulation functions. Shares family traits like low IQ and high accuracy but differs in pinout and package compared to SOT-23-5 variants. Designed for applications prioritizing space efficiency and integrated protection features.

Replacement Considerations

Check for direct substitutes within the S-1701 series offering identical output voltages and package dimensions. Verify electrical parameter equivalence before substitution. Consult official cross-reference lists for approved alternatives.
