BD3573FP-E2

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

The BD3573FP-E2 is a low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a fixed 3.3 V output with a maximum continuous current of 500 mA. The device operates within an input voltage range of 4.5 V to 36 V and features a typical dropout voltage of 250 mV, with a maximum of 480 mV. Key electrical parameters include a quiescent current of 30 uA, line regulation of 10 mV, load regulation of 20 mV, and a typical power supply rejection ratio (PSRR) of 55 dB. It is housed in a TO-252-5 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 exact suffix against official ROHM documentation, as the provided model differs from the verified BD3573YFP-ME2. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure the TO-252-5 package matches your PCB footprint requirements before ordering.

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

Select this component when a fixed 3.3 V rail is required with moderate current capacity up to 500 mA. The wide input voltage range allows flexibility in system design. Verify that the thermal performance in the TO-252-5 package meets the application's heat dissipation needs under maximum load conditions.
