S-13R1A17-M5T1U3

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

The S-13R1A17-M5T1U3 is a CMOS positive voltage regulator from the S-13R1 Series, manufactured by ABLIC Inc. It provides a fixed output voltage of 1.7 V with an accuracy of ±1.0%. The device supports an input voltage range of 2.0 V to 5.5 V and delivers up to 150 mA of output current. Key electrical characteristics include a typical dropout voltage of 150 mV at 100 mA, a ripple rejection ratio of 70 dB, and low current consumption of 5 μA during operation. It features reverse current protection, overcurrent protection, and thermal shutdown circuits.

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

• Built-in reverse current protection function limits reverse current flow from the output to the input pin.
• Includes overcurrent protection circuit to prevent damage from excessive load currents or short circuits.
• Thermal shutdown circuit activates to stop regulation when junction temperature exceeds safe limits.
• Supports ceramic capacitors of 1.0 μF or more for both input and output stabilization.

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

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

Verify the specific product type 'A' configuration, which includes active high ON/OFF logic, discharge shunt function, and constant current source pull-down. Confirm the package designation M5T1 corresponds to the SOT-23-5 form factor with tape packing. Ensure environmental compliance codes match lead-free and halogen-free requirements before finalizing procurement orders.

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

Select this component for applications requiring a stable 1.7 V rail with minimal quiescent current. The SOT-23-5 package suits space-constrained designs. Consider the discharge shunt feature if rapid output voltage decay is required upon shutdown. Verify that the application load does not exceed the 150 mA limit while respecting the package's power dissipation constraints under varying ambient temperatures.

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

This part belongs to the S-13R1 Series, a family of 5.5 V input, 150 mA voltage regulators developed using CMOS technology. The series emphasizes low dropout voltage, high accuracy, and low current consumption. The 'A' suffix denotes specific internal logic functions regarding the ON/OFF pin and discharge capabilities, distinguishing it from B, C, and D types within the same series.

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

Direct substitutes within the S-13R1 series include other fixed voltage variants such as S-13R1A18-M5T1U3 (1.8 V) or S-13R1A15-M5T1U3 (1.5 V), provided the voltage level matches the design requirement. Cross-series replacements require verification of pin compatibility, current ratings, and package dimensions.
