BD33GA3MEFJ-LBH2

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

The BD33GA3MEFJ-LBH2 is a single-output fixed low-dropout linear regulator manufactured by ROHM Semiconductor. It provides a stable 3.3 V output with a maximum current capacity of 300 mA. The device operates within an input voltage range of 4.5 V to 14 V and supports a maximum power dissipation of 2.11 W. It features a typical dropout voltage of 600 mV at full load and maintains a quiescent current of 600 uA. The component is housed in an HTSOP-J8 surface-mount package and is rated for industrial-grade operation across a temperature range of -40°C to +105°C.

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

Verify the specific suffix LBH2 against official ROHM documentation to confirm package and tape specifications, as ordering codes define physical attributes. Confirm the NRND status with the manufacturer before finalizing procurement plans, as this designation indicates the component is not recommended for new designs. Ensure compatibility with existing inventory strategies given the end-of-life implications.

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

Select this regulator when a fixed 3.3 V rail is required with moderate current demands up to 300 mA. The HTSOP-J8 package suits space-constrained surface-mount layouts. Consider the 600 mV dropout characteristic relative to the minimum 4.5 V input requirement. Evaluate the NRND status carefully; while suitable for maintaining existing production, it may not be ideal for long-term new product development without a confirmed replacement strategy.
