BD33IC0VEFJ-CE2

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

The BD33IC0VEFJ-CE2 is a fixed-output low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 3.3 V output with a maximum continuous current of 1 A. The device operates within an input voltage range of 2.4 V to 5.5 V and features a typical dropout voltage of 400 mV at full load, with a maximum of 900 mV. It maintains line and load regulation at 25 mV. The quiescent current is 5 uA. It is housed in an HTSOP-J8 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 specific suffix CE2 matches the required tape-and-reel packaging configuration for your assembly line. Confirm that the HTSOP-J8 footprint aligns with your PCB design guidelines. Ensure the AEC-Q100 qualification meets your system's functional safety requirements. Check for any recent lifecycle status updates regarding this specific part number before finalizing procurement plans.

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

Select this component when a 3.3 V rail is needed for automotive applications requiring 1 A capacity. The 2.4 V minimum input voltage allows operation close to battery discharge levels. The wide -40°C to +125°C range suits under-hood environments. Compare dropout characteristics against other LDOs if headroom is limited. Verify compatibility with external capacitor values specified in the official datasheet for stability.

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

This part belongs to ROHM's automotive LDO regulator family designed for high reliability. It complements other variants like the BD33IC0MEFJ-CE2, which includes additional watchdog timer and voltage detector functions. The BD33IC0VEFJ-CE2 focuses on core regulation performance without extra monitoring peripherals, offering a streamlined solution for standard voltage conversion tasks in automotive electronics.

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

The BD33IC0MEFJ-CE2 is a related variant but includes additional features not present in the VEJ version. Direct pin-to-pin substitution requires verifying if the extra watchdog or detector functions are compatible with the target circuit design. No other direct substitutes are confirmed in the provided documentation.
