BD3930FP-E2

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

The BD3930FP-E2 is a low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor, designed for high-voltage applications with low quiescent current. It provides a fixed 3.3 V output with a maximum continuous output current of 500 mA. The device operates within an input voltage range of 4.5 V to 25 V and features a typical dropout voltage of 780 mV at full load, with a maximum specified dropout of 1.1 V. It incorporates internal protection mechanisms including thermal shutdown and over-current protection. The component is housed in a TO-252-3 surface-mount package and supports an operating temperature range from -40°C to +125°C.

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

Verify the specific suffix E2 for RoHS compliance and lead time requirements. Confirm availability status as distribution channels may list this part as discontinued or not recommended for new designs. Ensure the TO-252-3 package matches your PCB footprint. Check for alternative sources if original manufacturer stock is limited.

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

Select this component when a stable 3.3 V rail is required from inputs between 4.5 V and 25 V. The 500 mA output capability suits moderate load applications. Consider the thermal performance in the TO-252-3 package under high ambient temperatures. Verify that the low quiescent current meets system standby power constraints compared to standard LDO alternatives.
