BD33IA5MEFJ-ME2 Description

Short technical summary and product information.

The ROHM Semiconductor BD33IA5MEFJ-ME2 is a silicon monolithic integrated circuit designed as a 0.5A Low Dropout (LDO) linear voltage regulator. This device provides a stable fixed output voltage of 3.3V, suitable for various power management applications.

 

Key electrical specifications include an input voltage range of 2.5V to 5.5V and a maximum output current of 0.5A. It features built-in protection circuits such as Over Current Protection (OCP) and Thermal Shutdown (TSD) to safeguard the IC from damage under fault conditions. The regulator also includes an Enable (EN) pin for circuit ON/OFF control, allowing for a shutdown current of typically 0μA.

 

The BD33IA5MEFJ-ME2 is housed in an 8-HTSOP-J package, a surface-mount type designed for efficient heat dissipation. Its operating temperature range is -40°C to +105°C, making it suitable for a wide array of environmental conditions. The device is AEC-Q100 qualified, indicating its suitability for automotive applications.
