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
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.

... Micrel, Inc. Applications Information The MIC29510 and MIC29512 are high performance low-dropout voltage regulators suitable for all moderate to high-current voltage regulator applications. Their 600mV of dropout voltage at full load make them especially valuable in battery powered systems and as high efficiency noise filters applications. Unlike older NPN-pass transistor designs, ...

... Input and GND is recommended. This capacitor should have good characteristics to above 250kHz. Transient Response and 5V to 3.3V Conversion The MIC29510/2 have excellent response to variations in input voltage and load current. By virtue of their low dropout voltage, these devices do not saturate into dropout as readily as similar NPN-based designs. A 3.3V output Micrel LDO will maintain full speed and performance with an input supply as low as 4 ...
