MIC29300-3.3BU Description

Short technical summary and product information.

The MIC29300-3.3BU is a high-current, low dropout linear voltage regulator designed for applications requiring a stable 3.3V output at up to 3A. Manufactured by Micrel Inc., this device ensures a maximum dropout voltage of just 370mV under full load, enabling efficient operation even when input-to-output voltage margins are tight. The output voltage is guaranteed to within 1% accuracy, making it suitable for precision power supply rails.

 

This regulator includes robust protection features such as reverse-battery and load dump protection, enhancing reliability in automotive and industrial environments. The extremely fast transient response helps maintain output voltage stability during rapid load changes, reducing the need for large output capacitors.

 

The MIC29300-3.3BU is packaged in a TO-220-5 through-hole package, facilitating easy integration into power supply designs. With a standard package quantity of 50 units, it is suitable for both prototyping and production runs. The device is RoHS3 compliant and has an MSL rating of 1, indicating unlimited floor life before soldering.
