BU33SD5WG-TR Description

Short technical summary and product information.

The ROHM Semiconductor BU33SD5WG-TR is a high-performance, 1-channel, 500mA CMOS LDO regulator designed for portable electronic devices. It features excellent noise and load response characteristics while maintaining low circuit current consumption of 33µA.

 

Key specifications include an input voltage range of 1.7V to 6.0V and an output current capability up to 500mA. The regulator provides a fixed 3.3V output with high accuracy of ±2.0% and offers a high ripple rejection ratio of 68dB at 1kHz. It is compatible with small ceramic capacitors, requiring a minimum of 0.47µF for both input and output.

 

Integrated protection features include Over Current Protection (OCP) and Thermal Shutdown (TSD), enhancing device reliability. The device also features an Output Voltage ON/OFF control pin for power management.

 

Packaged in a compact 5-SSOP (SC-74A, SOT-753) surface-mount package, the BU33SD5WG-TR is suitable for space-constrained applications such as camera modules and other electronic devices utilizing microcontrollers or logic circuits.
