描述 Description

The MIC29710 and MIC29712 are high-current, high-accuracy, low-dropout voltage regulators featuring fast transient recovery from input voltage surges and output load current changes. These regulators use a PNP pass element that features proprietary Super βeta PNP? process.

The MIC29710/2 is available in two versions: the 3-pin fixed output MIC29710 and the 5-pin adjustable output voltage MIC29712. All versions are fully protected against overcurrent 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 MIC29710/2 is available in the standard 3- and 5-pin TO-220 package with an operating junction temperature range of 0°C to +125°C.

For applications requiring even lower dropout voltage or input voltage greater than 16V, see the MIC29750/29752.
