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 rating. Sustained junction temperatures above that maximum can impact device reliability.

APPLICATION INFORMATION
The MIC49150 is an ultra-high performance,
low-dropout linear regulator designed for high current
applications requiring fast transient response. The
MIC49150 utilizes two input supplies, significantly
reducing dropout voltage, perfect for low-voltage,
DC-to-DC conversion. The MIC49150 requires a
minimum of external components and obtains a
bandwidth of up to 10 MHz. As a μCap regulator, the
output is tolerant of virtually any type of capacitor
including ceramic type and tantalum type capacitors.
The MIC49150 regulator is fully protected from damage
due to fault conditions, offering linear current limiting
and thermal shutdown.
4.1
Bias Supply Voltage
VBIAS, requiring relatively light current, provides power
to the control portion of the MIC49150. VBIAS requires
approximately 33 mA for a 1.5A load current. Dropout
conditions require higher currents. Most of the biasing
current is used to supply the base current to the pass
transistor. This allows the pass element to be driven
into saturation, reducing the dropout to 300 mV at a
1.5A load current. Bypassing on the bias pin is
recommended to improve performance of the regulator
during line and load transients.
Small ceramic capacitors from VBIAS to ground help
reduce high frequency noise from being injected into
the control circuitry from the bias rail and are good
design practice. Good bypass techniques typically
include one larger capacitor such as 1 μF ceramic and
smaller valued capacitors such as 0.01 μF or 0.001 μF
in parallel with that larger capacitor to decouple the bias
supply. The VBIAS input voltage must be 1.6V above the
output voltage with a minimum VBIAS input voltage of
3V.
4.2
Input Supply Voltage
VIN provides the high current to the collector of the pass
transistor. The minimum input voltage is 1.4V, allowing
conversion from low-voltage supplies.
4.3
operating temperature range and are the most stable
type of ceramic capacitors. Z5U and Y5V dielectric
capacitors change value by as much as 50% and 60%
respectively over their operating temperature ranges.
To use a ceramic chip capacitor with Y5V dielectric, the
value must be much higher than an X7R ceramic or a
tantalum capacitor to ensure the same capacitance
value over the operating temperature range. Tantalum
capacitors have a very stable dielectric (10% over their
operating temperature range) and can also be used
with this device.
4.4
Input Capacitor
An input capacitor of 1 μF or greater is recommended
when the device is more than 4 inches away from the
bulk supply capacitance, or when the supply is a
battery. Small, surface-mount, ceramic chip capacitors
can be used for the bypassing. The capacitor should be
placed within 1 inch of the device for optimal
performance. Larger values will help to improve ripple
rejection by bypassing the input to the regulator, further
improving the integrity of the output voltage.
4.5
Thermal Design
Linear regulators are simple to use. The most
complicated design parameters to consider are thermal
characteristics. Thermal design requires the following
application-specific parameters:
•
•
•
•
•
Maximum Ambient Temperature (TA)
Output Current (IOUT)
Output Voltage (VOUT)
Input Voltage (VIN)
Ground Current (IGND)
First, calculate the power dissipation of the regulator
from these numbers and the device parameters from
this data sheet.
EQUATION 4-1:
P D = V IN I IN + V BIAS I BIAS – V OUT I OUT
Output Capacitor
The MIC49150 requires a minimum of output
capacitance to maintain stability. However, proper
capacitor selection is important to ensure desired
transient response. The MIC49150 is specifically
designed to be stable with virtually any capacitance
value and ESR. A 1 μF ceramic chip capacitor should
satisfy most applications. Output capacitance can be
increased without bound. See Typical Performance
Curves for examples of load transient response.
The input current will be less than the output current at
high output currents as the load increases. The bias
current is a sum of base drive and ground current.
Ground current is constant over load current. Then the
heat sink thermal resistance is determined with this
formula:
X7R dielectric ceramic capacitors are recommended
because of their temperature performance. X7R-type
capacitors change capacitance by 15% over their

PD
The heat sink may be significantly reduced in
applications where the maximum input voltage is
known and 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 the MIC49150
allow significant reductions in regulator power
dissipation and the associated heat sink without
compromising performance. When this technique is
employed, a input and regulator ground.
4.6
θCA is reduced because Pins 5 through 8 can now be
soldered directly to a ground plane which significantly
reduces the case-to-sink thermal resistance and sink to
ambient thermal resistance.
Low-dropout linear regulators from Microchip are rated
to a maximum junction temperature of 125°C. It is
important not to exceed this maximum junction
temperature during operation of the device. To prevent
this maximum junction temperature from being
exceeded, the appropriate ground plane heat sink must
be used.
Minimum Load Current
The MIC49150, unlike most other high current
regulators, does not require a minimum load to
maintain output voltage regulation.
4.7
Power MSOP-8 Thermal
Characteristics
One of the secrets of the MIC49150’s performance is
its power MSOP-8 package featuring half the thermal
resistance of a standard MSOP-8 package. Lower
thermal resistance means more output current or
higher input voltage for a given package size.
Lower thermal resistance is achieved by joining the
four ground leads with the die attach paddle to create a
single-piece electrical and thermal conductor. This
concept has been used by MOSFET manufacturers for
years, proving very reliable and cost effective for the
user.
FIGURE 4-1:
Thermal Resistance
Figure 4-2 shows copper area versus power
dissipation with each trace corresponding to a different
temperature rise above ambient.
From these curves, the minimum area of copper
necessary for the part to operate safely can be
determined. The maximum allowable temperature rise
must be calculated to determine operation along which
curve.
Thermal resistance consists of two main elements, θJC
(junction-to-case thermal resistance) and θCA
(case-toambient thermal resistance). See Figure 4-1.
θJC is the resistance from the die to the leads of the
package. θCA is the resistance from the leads to the
ambient air and it includes θCS (case-to-sink thermal
resistance) and θSA (sink-to-ambient thermal
resistance).
Using the power MSOP-8 reduces the θJC dramatically
and allows the user to reduce θCA. The total thermal
resistance,
θJA
(junction-to-ambient
thermal
resistance) is the limiting factor in calculating the
maximum power dissipation capability of the device.
Typically, the power MSOP-8 has a θJA of 80°C/W, this
is significantly lower than the standard MSOP-8 which
is typically 160°C/W.

EQUATION 4-6:
P D = 1.8V 730mA + 3.3V 30mA – 1.2V 750mA
At full current, a small percentage of the output current
is supplied from the bias supply, therefore the input
current is less than the output current.

P D = 513mW
EQUATION 4-3:
T = T J MAX – T A MAX
Where:
TJ(MAX) = 125°C
TA(MAX) = Maximum ambient operating temperature
For example, the maximum ambient temperature is
50°C, the ΔT is determined as follows:
EQUATION 4-4:
T = 125C – 50C = 75C
Using Figure 4-2, the minimum amount of required
copper can be determined based on the required
power dissipation. Power dissipation in a linear
regulator is calculated as follows:
EQUATION 4-5:
P D = V IN I IN + V BIAS I BIAS – V OUT I OUT
Using a typical application of 750 mA output current,
1.2V output voltage, 1.8V input voltage and 3.3V bias
voltage, the power dissipation is as follows:
From Figure 4-2, the minimum current of copper
required to operate this application at a ΔT of 75°C is
less than 100 mm2.
4.8
Quick Method
Determine the power dissipation requirements for the
design along with the maximum ambient temperature
at which the device will be operated. Refer to
Figure 4-3, which shows safe operating curves for
three different ambient temperatures: 25°C, 50°C, and
85°C. From these curves, the minimum amount of
copper can be determined by knowing the maxi-mum
power dissipation required. If the maximum ambient
temperature is 50°C and the power dissipation is as
above, 513 mW, the curve in Figure 4-3 shows that the
required area of copper is less than 100 mm2.
The θJA of this package is ideally 80°C/W, but it will
vary depending upon the availability of copper ground
plane to which it is attached.
4.9
Adjustable Regulator Design
The MIC49150 adjustable version allows programming
the output voltage anywhere between 0.9V and 5V.
Two resistors are used. The resistor value between
VOUT and the adjust pin should not exceed 10 kΩ.
Larger values can cause instability. The resistor values
are calculated by:

Enable
The fixed output voltage versions of the MIC49150
feature an active-high enable input (EN) that allows
on/off control of the regulator. Current drain reduces to
“zero” when the device is shutdown, with only
microamperes of leakage current. The EN input has
TTL/CMOS compatible thresholds for simple logic
interfacing. EN may be directly tied to VIN and pulled up
to the maximum supply voltage.

contained in Microchip's Data Sheets. Attempts to breach these code protection features, most likely, cannot be accomplished
without violating Microchip's intellectual property rights.
•
Microchip is willing to work with any customer who is concerned about the integrity of its code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of its code. Code protection does not
mean that we are guaranteeing the product is "unbreakable." Code protection is constantly evolving. We at Microchip are
committed to continuously improving the code protection features of our products. Attempts to break Microchip's code protection
feature may be a violation of the Digital Millennium Copyright Act. If such acts allow unauthorized access to your software or
other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication is provided for the sole
purpose of designing with and using Microchip products. Information regarding device applications and the like is provided
only for your convenience and may be superseded by updates.
It is your responsibility to ensure that your application meets
with your specifications.

IN NO EVENT WILL MICROCHIP BE LIABLE FOR ANY INDIRECT, SPECIAL, PUNITIVE, INCIDENTAL OR CONSEQUENTIAL LOSS, DAMAGE, COST OR EXPENSE OF ANY KIND
WHATSOEVER RELATED TO THE INFORMATION OR ITS
USE, HOWEVER CAUSED, EVEN IF MICROCHIP HAS
BEEN ADVISED OF THE POSSIBILITY OR THE DAMAGES
ARE FORESEEABLE. TO THE FULLEST EXTENT
ALLOWED BY LAW, MICROCHIP'S TOTAL LIABILITY ON
ALL CLAIMS IN ANY WAY RELATED TO THE INFORMATION
OR ITS USE WILL NOT EXCEED THE AMOUNT OF FEES, IF
ANY, THAT YOU HAVE PAID DIRECTLY TO MICROCHIP
FOR THE INFORMATION. Use of Microchip devices in life support and/or safety applications is entirely at the buyer's risk, and
the buyer agrees to defend, indemnify and hold harmless
Microchip from any and all damages, claims, suits, or expenses
resulting from such use. No licenses are conveyed, implicitly or
