Microchip | MIC29712WT

The MIC29712WT is a high-current, high-accuracy, low-dropout voltage regulator featuring fast transient recovery from input voltage surges and output load current changes. This regulator uses a PNP pass element that features Micrel’s proprietary Super ßeta PNP™ process.

The MIC29710/2 is available in two versions: the three pin fixed output MIC29710 and the five pin adjustable output voltage MIC29712. All versions are fully protected against over current faults, reversed lead insertion, over temperature operation, and positive and negative transient voltage spikes.

A TTL compatible enable (EN) control pin supports external on/off control. If on/off control is not required, the device may be continuously enabled by connecting EN to IN. The MIC29712WT is available in the standard three and five pin TO-220 package with an operating junction temperature range of 0°C to +125°C.
