LE30ABD  

Linear & Switching Voltage Regulators

LE30ABD Description

The LE30ABD is a linear voltage regulator designed by STMicroelectronics, offering a fixed output voltage of 3V with a maximum output current of 100mA. This regulator is designed for surface mount applications and comes in an 8SO package. It features a maximum input voltage of 18V and a dropout voltage of 0.5V at 100mA, ensuring efficient operation even at low input-to-output voltage differentials. The regulator includes an enable control feature, allowing for power saving and dynamic control of the output voltage. It also offers over-current and over-temperature protection, enhancing reliability and safety in various applications. Despite being marked as obsolete, the LE30ABD remains a robust solution for applications requiring a stable 3V supply with low quiescent current and high power supply rejection ratio (PSRR).
