General Description
The MIC39300 and MIC39301 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 PNP pass element, the
MIC39300/1 offers extremely low dropout (typically 400mV at
3.0A) and low ground current (typically 36mA at 3.0A).
The MIC39300/1 is ideal for PC add-in cards that need to
convert from standard 5V or 3.3V down to new, lower core
voltages. A guaranteed maximum dropout voltage of 500mV
over all operating conditions allows the MIC39300/1 to pro-
vide 2.5V from a supply as low as 3V. The MIC39300/1 also
has fast transient response for heavy switching applications.
The device requires only 47
μ
F of output capacitance to
maintain stability and achieve fast transient response
The MIC39300/1 is fully protected with overcurrent limiting,
thermal shutdown, reversed-battery protection, reversed-
leakage protection, and reversed-lead insertion. 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 packages and is an ideal upgrade
to older, NPN-based linear voltage regulators.
