BD7800FP-E2 is listed in the Voltage Regulators - Linear, Low Drop Out (LDO) Regulators range at ChipApex. The manufacturer field lists Rohm Semiconductor. Its product description is IC REG LINEAR 5A. Review the specifications below when checking this part for your BOM.
The BD7800FP-E2 is a low-dropout (LDO) linear voltage regulator manufactured by ROHM Semiconductor. It provides a fixed output current of 0.5A with a maximum dropout voltage of 700 mV and a minimum operating temperature of -40°C. The device features a maximum input bias current of 550 µA and operates within a maximum junction temperature range up to +105°C. Packaged in the TO-252-3 format, it is designed for surface-mount applications requiring stable voltage regulation under varying load conditions.
Verify component authenticity through authorized distributors. Confirm RoHS compliance status via official datasheets. Check for obsolescence notices as availability may be limited. Ensure package integrity upon receipt. Validate part markings against official specifications.
Consider input-output voltage differential for thermal performance. Evaluate package thermal resistance for heat dissipation requirements. Verify compatibility with system ground references. Assess load transient response needs. Confirm operating temperature range suitability for the application environment.
This LDO regulator belongs to ROHM's low-power voltage regulation family. It complements other fixed-output regulators in the series. The TO-252-3 package offers a balance between current handling and board space efficiency. It serves as a solution for applications needing reliable regulation without complex external components.
Check for direct pin-compatible alternatives within the same manufacturer's portfolio. Verify electrical parameter equivalence for critical specifications. Consider package compatibility for existing PCB layouts. Review updated datasheets for any functional changes in successor parts.
