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 Microchip’s proprietary Super
βeta PNP pass element, the MIC39300/1/2 offers
extremely low dropout (typically 385 mV at 3.0A) and
low ground current (typically 36 mA at 3.0A).
The MIC39300/1/2 are 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
500 mV 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 have fast transient response for
heavy switching applications. The device requires only
47 µF of output capacitance to maintain stability and
achieve fast transient response.
The MIC39300/1/2 are 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 undervoltage and overcurrent conditions.
Offered in fixed voltages, the MIC39300/1 come in the
TO-220 and TO-263 (D2Pak) packages and are 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
(D2Pak) package.

Output voltage temperature coefficient is ΔVOUT(worst case) ÷ (TJ(max) – TJ(min)) where TJ(max) is +125°C
and TJ(min) is –40°C.
VDO = VIN – VOUT when VOUT decreases to 99% of its nominal output voltage with VIN = VOUT + 1V. For
output voltages below 2.5V, dropout voltage is the input-to-output voltage differential with the minimum
input voltage being 2.5V. Minimum input operating voltage is 2.5V.
IGND is the quiescent current. IIN = IGND + IOUT.
For a 1.8V device, VIN = 2.5V.
VEN ≤ 0.8V, VIN ≤ 8V, and VOUT = 0V.
Thermal regulation is defined as the change in output voltage at a time t after a change in power dissipation is applied, excluding load or line regulation effects. Specifications are for a 200 mA load pulse at
VIN = 8V for t = 10 ms.

Note 1:
The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable
junction temperature and the thermal resistance from junction to air (i.e., TA, TJ, JA). Exceeding the
maximum allowable power dissipation will cause the device operating junction temperature to exceed the
maximum +125°C rating. Sustained junction temperatures above +125°C can impact the device reliability.

APPLICATION INFORMATION
The MIC39300/1/2 are high-performance, low-dropout
voltage regulators suitable for moderate to high-current
voltage regulator applications. Its 550 mV dropout
voltage at full load makes it especially valuable in
battery-powered systems and as a high-efficiency
noise filter in post-regulator applications. Unlike older
NPN-pass transistor designs, where the minimum
dropout voltage is limited by the base-to-emitter
voltage drop and collector-to-emitter saturation
voltage, dropout performance of the PNP output of
these devices is limited only by the low VCE saturation
voltage.
A trade-off for the low dropout voltage is a varying base
drive requirement. Microchip’s Super βeta PNP
process reduces this drive requirement to only 2% to
5% of the load current.
The MIC39300/1/2 regulators are fully protected from
damage due to fault conditions. Current limiting is
provided. This limiting is linear; output current during
overload conditions is constant. Thermal shutdown
disables the device when the die temperature exceeds
the maximum safe operating temperature. Transient
protection allows device (and load) survival even when
the input voltage spikes above and below nominal. The
output structure of these regulators allows voltages in
excess of the desired output voltage to be applied
without reverse current flow.

The heat sink may be significantly reduced in
applications where the minimum input voltage is known
and is large compared with the dropout voltage. Use a
series input resistor to drop excessive voltage and
distribute the heat between this resistor and the
regulator. The low dropout properties of Microchip’s
Super βeta PNP regulators allow significant reductions
in regulator power dissipation and the associated heat
sink without compromising performance. When this
technique is employed, a capacitor of at least 1.0 μF is
needed directly between the input and regulator
ground.
Refer to Application Note 9 for further details and
examples on thermal design and heat sink
specification.
Thermal Design
VIN
IN
Linear regulators are simple to use. The most
complicated design parameters to consider are thermal
characteristics. Thermal design requires four
application-specific parameters:
•
•
•
•
•
Maximum ambient temperature (TA)
Output Current (IOUT)
Output Voltage (VOUT)
Input Voltage (VIN)
Ground Current (IGND)
Calculate the power dissipation of the regulator from
these numbers and the device parameters from this
datasheet, where the ground current is taken from the
data sheet.

Capacitor Requirements.
Output Capacitor
The MIC39300/1/2 requires an output capacitor to
maintain stability and improve transient response.
Proper capacitor selection is important to ensure
proper operation. The MIC39300/1/2 output capacitor
selection is dependent upon the ESR (equivalent
series resistance) of the output capacitor to maintain
stability. When the output capacitor is 47 µF or greater,
the output capacitor should have less than 1Ω of ESR.
This will improve transient response as well as promote
stability. Ultra low ESR capacitors, such as ceramic
chip capacitors may promote instability. These very low
ESR levels may cause an oscillation and/or
underdamped transient response. A low-ESR solid
tantalum capacitor works extremely well and provides
2018 Microchip Technology Inc.
MIC39300/01/02
good transient response and stability over temperature.
Aluminum electrolytics can also be used, as long as the
ESR of the capacitor is < 1Ω.
The value of the output capacitor can be increased
without limit. Higher capacitance values help to
improve transient response and ripple rejection and
reduce output noise.
4.3
Input Capacitor
An input capacitor of 1 µF or greater is recommended
when the device is more than 4 inches away from the
bulk AC supply capacitance or when the supply is a
battery. Small, surface mount, ceramic chip capacitors
can be used for bypassing. Larger values will help to
improve ripple rejection by bypassing the input to the
regulator, further improving the integrity of the output
voltage.
4.4
By virtue of its low dropout voltage, this device does not
saturate into dropout as readily as similar NPN-based
designs. When converting from 3.3V to 2.5V or 2.5V to
1.8V, the NPN-based regulators are already operating
in dropout, with typical dropout requirements of 1.2V or
greater. To convert down to 2.5V without operating in
dropout, NPN-based regulators require an input
voltage of 3.7V at the very least. The MIC39300/1
regulator will provide excellent performance with an
input as low as 3.0V or 2.5V. This gives the PNP-based
regulators a distinct advantage over older, NPN-based
linear regulators.
4.7
Enable Input
The MIC39301/2 feature an enable input for on/off
control of the device. The enable input’s shutdown
state draws “zero” current (only microamperes of
leakage). The enable input is TTL/CMOS compatible
for simple logic interface, but can be connected to up to
20V. When enabled, it draws approximately 15 µA.

The MIC39302 allows programming the output voltage
anywhere between 1.24V and 15.5V. Two resistors are
used. The resistor values are calculated by:
EQUATION 4-3:

R1 = R2 ------------- – 1
1.240
Minimum Load Current
The MIC39300/1/2 regulators are specified between
finite loads. If the output current is too small, leakage
currents dominate and the output voltage rises. A
10 mA minimum load current is necessary for proper
regulation.
4.6
When the error flag is not used, it is best to leave it
open. A pull-up resistor from FLG to either VIN or VOUT
is required for proper operation.
Transient Response and 3.3V to
2.5V and 2.5V to 1.8V Conversions
The MIC39300/1/2 has excellent transient response to
variations in input voltage and load current. The device
has been designed to respond quickly to load current
variations and input voltage variations. Large output
capacitors are not required to obtain this performance.
A standard 47 µF output capacitor, preferably tantalum,
is all that is required. Larger values help to improve
performance even further.
4.5
Low output voltage can be caused by a number of
problems, including an overcurrent fault (device in
current limit) or low input voltage. The flag is
inoperative during overtemperature shutdown.
Error Flag
Where VOUT is the desired output voltage. Figure 4-2
shows the component definition. Applications with
widely varying load currents may scale the resistors to
draw the minimum load current required for proper
operation (see Section 4.5 “Minimum Load
Current”).
The MIC39301 version features an error flag circuit that
monitors the output voltage and signals an error
condition when the voltage drops 5% below the
nominal output voltage. The error flag is an
open-collector output that can sink 10 mA during a fault
condition.
