S-1701A2833-M5T1G

Overview

The S-1701A2833-M5T1G is a low-dropout (LDO) voltage regulator manufactured by ABLIC Inc., featuring an integrated voltage detector. It provides two fixed output voltages of 2.8 V and 3.3 V with a maximum output current of 400 mA. The device operates within an input voltage range of 2 V to 6.5 V and maintains a typical dropout voltage of 140 mV at 100 mA, with a maximum of 210 mV. It exhibits a line regulation of 0.2 %/V and load regulation of 40 mV. Power dissipation is rated at 420 mW. The unit is housed in an SOT-23-5 package, supports surface mount installation, and functions across a temperature range of -40°C to +85°C.

Procurement Notes

Verify the specific part number against official ABLIC documentation to confirm pinout compatibility and electrical specifications. Ensure that the SOT-23-5 package footprint matches your PCB design requirements. Confirm operational temperature ranges align with your application environment. Check for any recent product change notifications or revisions that may affect performance or availability before finalizing procurement decisions.

Selection Notes

Select this component when a combined voltage regulator and detector solution is required to save board space. Consider the 400 mA output current capacity and the specific 2.8 V and 3.3 V fixed outputs. Evaluate the thermal performance given the 420 mW power dissipation rating in the SOT-23-5 package. Ensure the input voltage range of 2 V to 6.5 V suits your system's power supply architecture.

Part Context

This part belongs to the S-1701 series of combo voltage detectors and regulators from ABLIC. It is designed for applications requiring both regulated power and monitoring capabilities. The series offers various output voltage combinations and packages to suit different design constraints. This specific model integrates regulation and detection functions to simplify circuit design in space-constrained environments.

Replacement Considerations

Consult official ABLIC documentation for verified substitute part numbers within the S-1701 series that match the required output voltages and package type. Cross-reference specifications such as output current, dropout voltage, and operating temperature range to ensure functional equivalence. Verify pin-to-pin compatibility if direct replacement is intended without redesigning the PCB layout.
