MIC29510/29512
5A Fast-Response LDO Regulator
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
pin TO-220 package with an operating junction
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.
