S-13R1H35-I4T1U3

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

The S-13R1H35-I4T1U3 is a positive voltage regulator IC from the ABLIC S-13R1 series, manufactured using CMOS technology. It provides a fixed output voltage of 3.5 V with a maximum output current of 150 mA. The device operates within an input voltage range of 2.0 V to 5.5 V and features a typical dropout voltage of 150 mV at 100 mA. Key electrical parameters include a ripple rejection ratio of 70 dB typ., a quiescent current of 5 µA typ., and an operating temperature range of -40 °C to +85 °C. The package type is SC-82AB.

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

• Built-in reverse current protection function that limits reverse current flow from the output to the input pin without requiring an external protection diode.
• Integrated overcurrent protection circuit that prevents load current from exceeding the output transistor's capacity.
• Thermal shutdown circuit designed to prevent damage caused by overheating during operation.

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

• Portable electronic devices requiring low power consumption
• Battery-powered equipment utilizing ceramic capacitors for input and output filtering
• Systems needing stable voltage regulation under varying load conditions

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

Verify the specific output voltage accuracy and package availability directly with ABLIC Inc. or authorized distributors before procurement. Confirm that the SC-82AB package dimensions align with your PCB layout requirements. Ensure that the selected input and output capacitor values meet the stability criteria specified in the official datasheet for the S-13R1 series.

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

Select this component when a fixed 3.5 V output is required with a maximum load of 150 mA. It is suitable for applications where low quiescent current and high ripple rejection are critical. Ensure the input voltage remains within the 2.0 V to 5.5 V range. Consider the thermal performance if the device will operate near the upper limit of its temperature range.

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

This part belongs to the S-13R1 series of CMOS LDO voltage regulators from ABLIC. The series is characterized by low dropout voltage, high accuracy, and low current consumption. It is designed for use in portable devices and battery-operated equipment where power efficiency and space constraints are important factors.

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

Check for other parts within the S-13R1 series with different output voltages if 3.5 V is not strictly required. Verify compatibility with existing PCB footprints, as the SC-82AB package must match the design. Ensure that any substitute maintains the same reverse current protection and thermal shutdown features.
