BD33GC0WEFJ-E2

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

The BD33GC0WEFJ-E2 is a high-accuracy linear LDO voltage regulator manufactured by ROHM Semiconductor. It provides a fixed positive output of 3.3 V with a maximum load current capability of 1 A. The device operates within an input voltage range of 4.5 V to 14 V and maintains a typical dropout voltage of 0.6 V at full load. Key electrical specifications include a quiescent current of 0.6 mA, load regulation of 25 mV (0 to 1 A), and ripple rejection of 60 dB. It features integrated protection circuits including overcurrent, thermal shutdown, and soft start functionality.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrated overcurrent protection and thermal shutdown circuits prevent IC damage during short circuits or overload conditions.
• Built-in soft start function limits inrush current during power-up sequences.
• On/off switch capability reduces circuit current to 0 µA when disabled.

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

• Digital home appliances
• General-purpose electronic equipment requiring stable 3.3 V supply

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

Verify the specific suffix against official ROHM documentation to confirm package type and tape/reel specifications. Ensure compatibility with HTSOP-J8 footprint requirements. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement orders.

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

Select this component for applications requiring a fixed 3.3 V output up to 1 A with a wide input voltage range up to 14 V. Consider the 0.6 V dropout voltage and 0.6 mA quiescent current for efficiency calculations. Verify that ceramic output capacitors are used as recommended to ensure stability and longevity.
