BD3571YFP-ME2

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

The BD3571YFP-ME2 is a positive, fixed-output linear voltage regulator manufactured by Rohm Semiconductor. It provides a stable 5V output with a maximum current capability of 500mA. The device operates within an input voltage range of 5.5V to 36V and features a typical dropout voltage of 250mV at 200mA, with a maximum of 480mV. Key electrical parameters include a quiescent current of 30µA, ripple rejection of 55dB, line regulation of 10mV, and load regulation of 20mV. It 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 component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix ME2 matches design requirements. Check for end-of-life status as indicated by final sales designation. Ensure compliance with RoHS directives and functional safety support categories if applicable to the target application environment.

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

Select this regulator when a fixed 5V output is required with high input voltage tolerance up to 36V. The TO-252-3 package suits applications needing moderate heat dissipation. Consider the 500mA output limit and 250mV typical dropout for headroom calculations. Verify that the fixed output meets system needs, as adjustable variants exist in the same family.

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

This component belongs to the BD3571 series of high-voltage LDO regulators designed by Rohm Semiconductor. It shares architectural similarities with other members like the BD3572YFP-ME2 but differs in output configuration, offering a fixed 5V rather than adjustable output. The series targets automotive and industrial environments requiring robust voltage regulation under varying load and input conditions.

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

Direct substitutes may include other ROHM LDOs with similar pinouts and specifications, such as the BD3572YFP-ME2 if adjustable output is acceptable. Cross-reference datasheets for exact electrical parameter matching before substitution.
