Additional Details

The ADP3339AKCZ285RL7 is a 2.85V fixed-output LDO regulator. It boasts a high output accuracy, typically within ±1%, ensuring precise voltage regulation for sensitive applications. The low dropout voltage allows it to maintain regulation even when the input voltage is only slightly higher than the output voltage. The device's low quiescent current minimizes power consumption in standby or light-load conditions. The integrated short-circuit and over-temperature protection features enhance the device's reliability and protect it from damage. The enable/disable pin allows for external control of the regulator's operation, enabling power saving or system reset functionality. This particular part is often favored where tight voltage tolerances and low power consumption are paramount.
