General Description

The MIC29510 and MIC29512 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 Micrel’s proprietary Super ßeta

PNP™ process.

The MIC29510/2 is available in two versions: the three pin

fixed output MIC29510 and the five pin adjustable output

voltage MIC29512. All versions are fully protected against

overcurrent faults, reversed input polarity, reversed lead

insertion, overtemperature 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 MIC29510/2 is available in the standard three and five

temperature range of 0°C to +125°C.

For applications requiring even lower dropout voltage,

input voltage greater than 16V, or an error flag, see the

MIC29500/29501/29502/29503.
