S-13R1D23-A4T2U3

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

The S-13R1D23-A4T2U3 is a CMOS positive voltage regulator with a fixed 2.3 V output, housed in an HSNT-4 (1010) package. It supports a 2.0 V to 5.5 V input range and delivers up to 150 mA output current. Key electrical parameters include ±1.0% output accuracy, 70 dB ripple rejection at 1 kHz, and a typical dropout voltage of 0.28 V at 100 mA. Operating current is 5 μA typ., with reverse current limited to 0.09 μA max.

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

• Integrated reverse current protection prevents backflow from the output to the input pin without requiring external diodes.
• Built-in overcurrent protection limits output current to safeguard the internal transistor against short circuits.
• Thermal shutdown circuit automatically halts regulation when junction temperature exceeds safe operating limits.
• ON/OFF control logic allows for active high operation to minimize power consumption during standby.

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

• Constant-voltage power supply for battery-powered devices
• Power management for portable electronic equipment
• Voltage regulation for home electric appliances
• Power supply stages for mobile phone applications

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

Verify the specific ordering suffix A4T2U3 confirms the HSNT-4 (1010) surface-mount package and tape reel packing configuration. Ensure the D-type designation matches system requirements for disabled discharge shunt and pull-down functions. Confirm lead-free and halogen-free compliance status prior to final procurement authorization.

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

Select this component for designs requiring low quiescent current and robust reverse current blocking capabilities. The HSNT-4 package offers a compact footprint suitable for space-constrained PCB layouts. Verify that the application load does not exceed the 150 mA limit while respecting the package's thermal dissipation constraints under maximum ambient temperatures.

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

This device belongs to the S-13R1 series of low-dropout regulators manufactured by ABLIC Inc. The series utilizes CMOS technology to achieve high efficiency and low power consumption. The D-type variant specifically lacks internal discharge shunt and constant current source pull-down features found in other series types.

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

Direct substitutes within the same series include S-13R1B23-A4T2U3 or S-13R1C23-A4T2U3 if different ON/OFF pin behaviors are acceptable. Cross-manufacturer replacements require matching the 150 mA current rating, 2.3 V output voltage, and HSNT-4 package dimensions.
