S-13R1D36-I4T1U3

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

The S-13R1D36-I4T1U3 is a CMOS positive voltage regulator IC from the S-13R1 Series by ABLIC Inc. It provides a fixed output voltage of 3.6 V with an accuracy of ±1.0%. The device supports a maximum output current of 150 mA and operates within an input voltage range of 2.0 V to 5.5 V. Key electrical characteristics include a typical dropout voltage of 150 mV at 100 mA, a ripple rejection ratio of 70 dB typ., and low current consumption of 5 μA typ. during operation. It features reverse current protection limiting reverse flow to 0.09 μA max.

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

• Built-in reverse current protection function prevents current flow from the VOUT pin to the VIN pin without requiring an external protection diode.
• Integrated overcurrent protection circuit limits load current to protect the output transistor, complemented by a thermal shutdown circuit that halts regulation at high junction temperatures.
• Includes an ON/OFF control circuit for power management, allowing the device to enter a low-power state when inactive.

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

• Constant-voltage power supply for battery-powered devices
• Constant-voltage power supply for portable equipment
• Constant-voltage power supply for home electric appliances
• Constant-voltage power supply for mobile phones

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

Verify the specific package type (SOT-23-5, SC-82AB, or HSNT-4) required for your design, as the datasheet lists multiple options for the S-13R1 series. Confirm environmental compliance details such as lead-free and halogen-free status directly with the manufacturer or authorized distributors before finalizing procurement specifications.

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

Select this component for applications requiring a fixed 3.6 V output with low quiescent current. Ensure the input voltage remains within the 2.0 V to 5.5 V range and that the load does not exceed 150 mA. Consider the package's power dissipation limits under expected operating conditions to avoid triggering the thermal shutdown circuit.

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

This part belongs to the S-13R1 Series, which utilizes CMOS technology to achieve low dropout voltage and high accuracy. The 'D' in the model number indicates a specific product type variant where both the discharge shunt function and constant current source pull-down are unavailable. The series is designed for stable operation using ceramic capacitors of 1.0 μF or more on both input and output pins.

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

Direct substitutes within the same series include other S-13R1 variants with different output voltages or package types, such as S-13R1D33-I4T1U3 for a 3.3 V output. Cross-series replacements like the S-13A1 series offer higher current capabilities but may differ in package dimensions and specific feature sets like pull-down functions.
