BD33GA3WEFJ-E2 Description

Short technical summary and product information.

The BD33GA3WEFJ-E2 from ROHM Semiconductor is a 300mA linear voltage regulator (LDO) designed for various digital appliance applications. This device offers a fixed output voltage of 3.3V with a high output accuracy of ±1%.

 

Key electrical specifications include an input voltage range of 4.5V to 14.0V and a maximum output current of 0.3A. The regulator incorporates built-in protection features such as over current protection (OCP), thermal shutdown (TSD), and a zero shutdown current mode (0µA typical). It also includes a soft start feature.

 

The BD33GA3WEFJ-E2 is available in an 8-HTSOP-J package, which is a surface-mount type measuring 4.90mm x 6.00mm x 1.00mm. The operating temperature range is from -25°C to +85°C, making it suitable for a wide array of environmental conditions. This LDO regulator is designed for use with ceramic capacitors, enabling smaller PCB layouts and longer operational life.
