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

Verify the specific suffix E2 against the official ROHM datasheet to confirm production line and package details. Ensure the HTSOP-J8 package matches the target PCB footprint. Confirm RoHS compliance status through the manufacturer's certification documents before finalizing procurement orders.

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

Select this regulator when a 3.3 V rail is required with up to 1 A capacity and an input voltage between 4.5 V and 14 V. Consider the 600 mV typical dropout voltage for headroom calculations. The HTSOP-J8 package offers thermal performance suitable for moderate power dissipation up to 2.11 W in surface-mount designs.

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

This component belongs to the BD33 series of LDO regulators from ROHM, designed for general consumer electronics. It shares the HTSOP-J8 package form factor with other variants in the family but differs in input voltage ranges and output current capabilities compared to models like the BD33IC0JEFJ-E2 or BD33HC5JEFJ.

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

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs if considering alternative LDO regulators with similar 3.3 V output and 1 A current ratings.
