S-13R1D24-I4T1U3

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

The S-13R1D24-I4T1U3 is a CMOS positive voltage regulator IC from the S-13R1 Series, manufactured by ABLIC Inc. It provides a fixed output voltage of 2.4 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 0.28 V at 100 mA, a typical operating current consumption of 5 μA, and a ripple rejection ratio of 70 dB at 1.0 kHz. The component features built-in reverse current protection limiting reverse flow to 0.09 μA max, overcurrent protection, and thermal shutdown circuits.

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

• Integrated reverse current protection function prevents backflow from the output to the input pin without requiring external diodes.
• Built-in discharge shunt circuit rapidly discharges output capacitance when the ON/OFF pin is set to the OFF level.
• Includes overcurrent protection and thermal shutdown circuits to safeguard against excessive load currents and overheating.

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 (SC-82AB) and environmental code (U for lead-free/halogen-free) match your design requirements. Confirm that the D-type product configuration aligns with your need for no internal pull-down or discharge functions on the ON/OFF pin. Ensure input and output capacitors meet the minimum 1.0 μF ceramic specification for stability.

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

Select this component if a fixed 2.4 V output is required with low quiescent current consumption. The D-type designation indicates the absence of internal discharge shunt and constant current source pull-down functions; verify this matches your system's power-off state requirements. Ensure the application stays within the -40°C to +85°C operating temperature range and respects the package power dissipation limits under high load conditions.

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 series offers various packages including SOT-23-5, SC-82AB, and HSNT-4 (1010). The 'D' in the model number specifies the functional variant regarding the ON/OFF pin behavior, specifically lacking internal discharge and pull-down circuits compared to other types in the series.

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

Cross-reference with other S-13R1 Series variants such as S-13R1A24, S-13R1B24, or S-13R1C24 if different ON/OFF pin behaviors are needed. Verify package compatibility if substituting between SOT-23-5, SC-82AB, or HSNT-4 formats.
