General Description
The Micrel MIC61150 is a 1.5A output, low input voltage,
single-supply regulator. This regulator operates over a
single input voltage range of 1.1V to 3.6V and offers an
ultra-low dropout less than 200mV over the entire
operating temperature range.
The MIC61150 is designed to drive digital circuits requiring
low voltages at high currents such as DSPs, FPGAs,
microcontrollers, etc. The regulator is available as a 1.0V
fixed-output voltage option or as an adjustable-output
voltage option.
The MIC61150 is stable with a 22µF, low-ESR ceramic
output capacitor, and includes protection features such as
thermal shutdown, current limiting and logic enable.
The MIC61150 is offered in two different packages: a low-
profile, leadless 10-pin 3mm x 3mm MLF® and a 10-pin
ePad MSOP. The MIC61150 has an operating junction
temperature range of −40°C to +125°C.

Functional Description
The MIC61150 is an ultra-high-performance, low-dropout
linear regulator designed for high-current applications
that require low input voltage operation. The MIC61150
operates from a single input supply and generates an
internal supply that is higher than the input voltage to
drive an on-chip N-Channel MOSFET. The N-Channel
MOSFET significantly reduces the dropout voltage when
compared to a traditional P-Channel MOSFET.
P-Channel MOSFETs are usually used in single-supply
low-dropout linear voltage regulators. However, for input
voltages below 1.5V, there is not sufficient gate drive to
turn on the P-Channel. To solve this issue, the
MIC61150 uses a simple internal charge pump to drive
the internal N-Channel MOSFET’s gate higher than the
input voltage, see Functional Diagram. The N-Channel
MOSFET greatly reduces the dropout voltage for the
same die area when compared to that of a P-Channel.
Other added benefits of the charge pump include the
ability to control the output voltage rise time and to
improve the power supply rejection ratio (PSRR). This is
accomplished by using the VCP supply to power the error
amplifier.
The other significant advantage of the MIC61150 over a
P-Channel regulator is its transient response. The N-
Channel in the follower configuration is much faster than
its P-channel counter part and is simpler to compensate.
Any type of output capacitor can be placed in parallel
with it as long as the minimum value output ceramic
capacitor is placed next to the MIC61150. See the
Output Capacitor section for specific details. Also, the
regulator is fully protected from damage due to fault
conditions by offering linear current limiting and thermal
shutdown.
Soft-Start
Soft-start reduces the power supply input surge current
at startup by controlling the output voltage rise time. The
input surge appears while the output capacitor is
charged up. A slower output rise time will draw a lower
input surge current.
The CP pin is the output of the internal charge pump.
The soft-start rise time is controlled by the external
capacitor connected from CP pin to GND. During soft-
start, the charge pump feeds a current to CCP. The
output voltage rise time is dependent upon the value of
CCP, the input voltage, output voltage and the current
limit. The value of the charge pump external capacitor
selected is recommended in the range of 0.1µF to 1µF,
although larger value capacitors can be used for a
longer turn-on time.
Input Capacitor
A 10µF ceramic input capacitor is all that is required for
most applications. However, fast load transient and low
headroom (VIN – VOUT) requires additional bulk bypass
capacitance to ensure that the regulator does not drop
out of regulation.
The input capacitor must be placed on the same side of
the board and next to the MIC61150 to minimize the
dropout voltage and voltage ringing during transient and
short circuit conditions. It is also recommended to use
two vias for each end of the capacitor to connect to the
power and ground plane.
X7R or X5R dielectric ceramic capacitors are
recommended because of their temperature
performance. X7R-type capacitors change capacitance
by 15% over their 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 in parallel with the ceramic capacitor(s).
See Typical Characteristics section for examples of load
transient response.
Output Capacitor
As part of the frequency compensation, the MIC61150
requires a 22µF ceramic output capacitor. However, any
other type of capacitor can be placed in parallel as long
as the 22µF ceramic output capacitor is placed next to
the MIC61150.
Output voltages below 0.8V require either a 47µF or
2x 22µF output capacitance for large output transients.
The increased output capacitance reduces the output
voltage drop caused by load transients, which increases
as a percentage of the output voltage as the output
voltage is lowered.
The output capacitor type and placement criteria are the
same as the input capacitor. See the Input Capacitor
section for a detailed description.
Minimum Load Current
The MIC61150 requires a minimum load of 10mA to
maintain output voltage regulation.

Adjustable Regulator Design
The MIC61150 adjustable version allows programming
the output voltage from 0.5V to 3.0V by placing a resistor
divider network (R1, R2) from VOUT to GND (see
Application Circuit). The high side of R1 should be
connected at the point-of-load for high-accuracy Kelvin
sensing. VOUT is determined by the following equation:

0.5VOUT Eq. 1
where VOUT is the desired output voltage.
The resistor (R2) value between the FB pin and GND is
selected to maintain a minimum 10mA load on the
output.
The resistor values are calculated from the previous
equation, resulting in the following:

Thermal Design
Linear regulators are simple to use. The most
complicated design parameters to consider are thermal
characteristics. To help reduce the thermal resistance,
the ePad (underneath the IC) should be soldered to the
PCB ground and the placement of thermal vias either
underneath or near the ePad is highly recommended.
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
datasheet:
PD = (VIN - VOUT) × IOUT + (VIN × IGND) Eq. 3
where the ground current is approximated by using
numbers from the Electrical Characteristics or Typical
Characteristics sections
For example, given an expected maximum ambient
temperature (TA) of 75°C with VIN = 1.2V, VOUT = 0.9V,
and IOUT = 1.5A, first calculate the expected PD using
Equation 1:
PD = (1.2V – 0.9V) × 1.5A + 1.2V × 0.015A
= 0.468W Eq. 4
Next, determnine the junction temperature for the
expected power dissipation above using the thermal
resistance (JA) of the 10-pin 3mm × 3mm MLF® (YML)
adhering to the following criteria for the PCB design:
1oz. copper and 100mm2 copper area for the
MIC61150.
TJ = (JA × PD) + TA
= (60.7°C/W × 0.468W) + 75°C
= 103.4°C Eq. 5

To determine the maximum power dissipation allowed
that would not exceed the IC’s maximum junction
temperature (125°C) when operating at a maximum
ambient temperature of 75°C by:
PD(MAX) = (TJ(MAX) – TA) / JA
= (125°C − 75°C) / (60.7°C/W)
= 0.824W Eq. 6
Thermal Measurements
It is always wise to measure the IC’s case temperature
to make sure that it is within its operating limits. Although
this might seem like a very elementary task, it is very
easy to get erroneous results. The most common
mistake is to use the standard thermal couple that
comes with the thermal voltage meter. This thermal
couple wire gauge is large, typically 22 gauge, and
behaves like a heatsink, resulting in a lower case
measurement.
There are two suggested methods for measuring the IC
case temperature: a thermal couple or an infrared
thermometer. If a thermal couple is used, it must be
constructed of 36 gauge wire or higher to minimize the
wire heatsinking effect. In addition, the thermal couple tip
must be covered in either thermal grease or thermal glue
to make sure that the thermal couple junction is making
good contact to the case of the IC. This thermal couple
from Omega (5SC-TT-K-36-36) is adequate for most
applications.
To avoid this messy thermal couple grease or glue, an
infrared thermometer is recommended. Most infrared
thermometers’ spot size are too large for an accurate
reading on small form factor ICs. However, an IR
thermometer from Optris has a 1mm spot size, which
makes it ideal for the 3mm × 3mm MLF® package. Also,
get the optional stand. The stand makes it easy to hold
the beam on the IC for long periods of time.
Enable
The MIC61150 features an active high enable input (EN)
that allows ON/OFF control of the regulator. The current
through the device reduces to near “zero” when the
device is shutdown, with only microamperes of leakage
current. The EN input may be directly tied to VIN or
driven by a voltage that is higher than VIN as long as the
voltage does not exceed the maximum operating rating
of the EN pin.
