BD70HC5JEFJ-E2

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

The BD70HC5JEFJ-E2 is a fixed-output low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a maximum output current of 1.5 A with a fixed output voltage type. The device operates within an input voltage range of 4.5 V to 8 V and supports a fixed output configuration. It features a typical dropout voltage of 0.6 V at full load and maintains an output accuracy of ±1.0% at 25°C. The regulator includes a shutdown function, thermal shutdown protection, and overcurrent protection circuits. It is housed in an HTSOP-J8 package suitable for surface mount installation.

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

Verify the specific suffix E2 to confirm the exact manufacturing lot and revision level. Confirm that the HTSOP-J8 package matches the target PCB footprint. Ensure the 1.5 A output current requirement aligns with the thermal dissipation capabilities of the final assembly. Check for RoHS compliance status if required by regional regulations.

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

Select this component when a stable 1.5 A supply is needed from a 4.5 V to 8 V source. The fixed output eliminates external resistor networks. Consider the 0.6 V dropout voltage for efficiency near the minimum input threshold. Verify that the operating temperature range of -25°C to +85°C meets the environmental requirements of the application.
