BD35269HFN-TR

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

The BD35269HFN-TR is a single-channel, positive fixed-output Low Dropout (LDO) linear voltage regulator manufactured by ROHM Semiconductor. It provides a nominal output voltage of 1.2V with a maximum input voltage range up to 4.5V or 5.5V depending on specific documentation variants. The device supports an output current of 1A and utilizes an 8-pin HSON package measuring 2.9x3.0x0.6mm. Key electrical characteristics include integrated enable control and adjustable soft-start functionality to manage inrush currents.

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

Verify the exact input voltage rating and output tolerance against the specific datasheet revision, as sources indicate variations between 4.5V and 5.5V max input ratings. Confirm the package marking code matches the HSON8 form factor. Ensure the supplier provides traceability documentation consistent with ROHM Semiconductor manufacturing standards for automotive or industrial grade components.

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

Select this component when a fixed 1.2V rail is required with 1A load capability in a minimal footprint. The integrated soft-start feature makes it suitable for systems requiring controlled power-up sequences. Compare thermal performance requirements against the HSON8 package dissipation limits if operating near the maximum input voltage differential.

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

This LDO belongs to ROHM's BD35 series of low-dropout regulators optimized for portable electronics and display drivers. The HSON8 package variant is part of a family designed to replace larger SOT packages while maintaining similar electrical performance profiles for system miniaturization.

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

Check pin-to-pin compatibility with other 1.2V fixed-output LDOs in HSON8 packages from ROHM or competitors. Verify that substitute parts support the same 1A continuous current and soft-start timing requirements.
