General Description
The MIC29710 and MIC29712 are high-current, high-accu-
racy, 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 Micrel’s proprietary Super ßeta PNP
The MIC29710 is available in the 3-pin fixed output and
the MIC29712 is available in the 5-pin adjustable output
voltage. Both versions are fully protected against
overcurrent
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 maybe continuously enabled by connecting EN to
IN.
The MIC29710 is available in the standard 3-pin TO-220
package the MIC29712 is available in the 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.
