MIC39300/39301/39302
3A, Low-Voltage Low-Dropout Regulator
General Description
Features
PNP
pass element, the MIC39300/1/2 offers extremely
The MIC39300, MIC39301 and MIC39302 are 3.0A low-
dropout linear voltage regulators that provide a low
voltage, high-current output with a minimum of external
components. Utilizing Micrel’s proprietary Super β eta
?
low dropout (typically 385mV at 3.0A) and low ground
current (typically 36mA at 3.0A).
The MIC39300/1/2 is ideal for PC add-in cards that need
to convert from standard 3.3V to 2.5V or 2.5V to 1.8V. A
guaranteed maximum dropout voltage of 500mV over all
operating conditions allows the MIC39300/1/2 to provide
2.5V from a supply as low as 3V, and 1.8V from a supply
as low as 2.5V. The MIC39300/1/2 also has fast transient
response for heavy switching applications. The device
requires only 47μF of output capacitance to maintain
stability and achieve fast transient response.
The MIC39300/1/2 is fully protected with overcurrent

Applications
The MIC39301 offers a TTL-logic compatible enable pin
and an error flag that indicates under voltage and over
current conditions. Offered in fixed voltages, the
MIC39300/1 comes in the TO-220 and TO-263 (D 2 Pak)
packages and is an ideal upgrade to older, NPN-based
linear voltage regulators. The MIC39302 adjustable option
allows programming the output voltage anywhere between
1.24V and 15.5V and is offered in a 5-Pin, TO-263 (D 2 Pak)
