BD3020HFP-TR

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

The BD3020HFP-TR is a linear voltage regulator IC from ROHM Semiconductor, featuring Advanced LDO technology for precise voltage regulation. It provides a fixed positive output of 5V with a maximum load current of 500mA. The device operates within an input voltage range up to 36V and maintains operation across an extended temperature range of -40°C to 125°C (TA). Key electrical parameters include a quiescent current of 130 µA and an operating supply current of 80 µA. It incorporates a watchdog timer (WDT) and a voltage detector for system monitoring. The component is housed in the HRP7 surface-mount package.

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

Verify the manufacturer designation carefully, as some distributor listings may incorrectly associate this part number with LAPIS Semiconductor despite ROHM being the primary manufacturer. Confirm the specific suffix TR indicates tape-and-reel packaging if reel quantity is required for assembly. Ensure the HRP7 package footprint matches your PCB design constraints before finalizing procurement orders.

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

Select this component when a fixed 5V output is required with moderate current demands up to 500mA. It is suitable for applications needing built-in fault protection via the integrated watchdog timer and voltage detector. Consider the 36V maximum input voltage rating for systems with higher supply rails. The wide operating temperature range makes it appropriate for automotive or industrial environments where thermal stability is critical.

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

This component belongs to ROHM's family of linear voltage regulators designed for power management applications. It is distinct from motor driver ICs such as the BD6222HPF, which serve different functions in brushless DC motor control. The BD3020HFP-TR focuses on precision voltage regulation rather than high-current switching or motor drive capabilities, fitting into the PMIC category for stable power delivery.

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

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pin compatibility and electrical specifications with alternative LDO regulators if sourcing issues arise, ensuring equivalent output voltage, current capacity, and package dimensions.
