BU33JA3DG-CTR

BU33JA3DG-CTR Description

The BU33JA3DG-CTR is a high-performance CMOS Low Dropout (LDO) regulator designed by Rohm Semiconductor. This regulator is specifically tailored for applications requiring a stable 3.3V output voltage with a maximum input voltage of 6V. It is capable of delivering a continuous output current of 300mA, making it suitable for a wide range of electronic devices. The regulator features a low dropout voltage of 0.2V at 300mA, ensuring efficient operation even when the input voltage is close to the output voltage. This efficiency is crucial for battery-powered devices where maximizing battery life is essential.

The BU33JA3DG-CTR is designed with a quiescent current of only 80 µA, which significantly reduces power consumption in standby mode. This low quiescent current is particularly beneficial for applications where power efficiency is a critical concern. The regulator also boasts a high Power Supply Rejection Ratio (PSRR) of 60dB at 1kHz, effectively filtering out noise from the power supply and ensuring a clean output voltage.
