S-13R1F13-M5T1U3

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The S-13R1F13-M5T1U3 is a CMOS positive voltage regulator from the ABLIC S-13R1 series, providing a fixed output of 1.3 V with a maximum load current of 150 mA. It operates within an input voltage range of 1.5 V to 5.5 V and features a typical quiescent current of 5 μA. The device incorporates reverse current protection, high ripple rejection, and thermal shutdown. It is housed in a compact SOT-23-5 surface-mount package and supports operation across a temperature range of -40°C to +85°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrated reverse current protection prevents backflow when the input voltage drops below the output level.
• High ripple rejection ratio ensures stable power delivery by suppressing input noise effectively.
• Ultra-low current consumption minimizes power drain during continuous operation.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Applications

• Battery-powered portable electronic devices requiring extended standby life

• Microcontroller system voltage regulation

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix M5T1U3 against official ABLIC documentation to confirm the exact package type and tape-and-reel specifications. Ensure compatibility with your PCB footprint for the SOT-23-5 form factor. Confirm that the fixed 1.3 V output aligns with your target circuit requirements before finalizing procurement.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed low-voltage rail is needed with minimal static power draw. The S-13R1 series is suitable for applications where reverse current flow must be prevented without external diodes. Consider the 150 mA limit and dropout characteristics relative to your minimum input voltage constraints.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the S-13R1 series of 150 mA LDO regulators featuring reverse current protection. Unlike standard LDOs, these ICs include internal circuitry to block current from flowing backward from the output to the input pin, enhancing safety in battery-operated systems where input sources may be disconnected or shorted.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct replacements within the same series include other S-13R1 variants with different fixed output voltages, such as S-13R1D16-I4T1U3 (1.6 V) or S-13R1C33-N4T1U3 (3.3 V), provided the voltage requirement differs. Verify pinout compatibility for the SOT-23-5 package when substituting.
