AS2830AT-3.3 Description

Short technical summary and product information.

The AS2830AT-3.3 is a positive fixed voltage regulator manufactured by Alpha Components. It is designed to provide a reliable 3.3V output voltage. The device includes built-in protection mechanisms against over-current faults, reversed load insertion, over-temperature operation, and positive and negative transient voltages.

Stability and performance are enhanced through the use of an output capacitor. For stable operation, a 22 µF aluminum electrolytic capacitor or a 10 µF solid tantalum capacitor between the output terminal and ground is recommended. Ripple rejection can be further improved by adding a capacitor between the ADJ pin and ground. The specific capacitor values required depend on whether the ADJ pin is bypassed.

Thermal considerations are important for optimal performance. The AS2830AT-3.3 has limiting circuitry for overload conditions, but it is necessary to avoid exceeding the maximum junction temperature. Proper mounting is required to ensure the best thermal flow, as the device case is electrically connected to the output.
