MIC5216
500mA-Peak Output LDO Regulator
Preliminary Information
General Description
Features
The MIC5216 is an efficient linear voltage regulator with high
peak output current capability, very low dropout voltage, and
better than 1% output voltage accuracy. Dropout is typically
10mV at light loads and less than 500mV at full load.
• Error Flag indicates undervoltage fault
• Guaranteed 500mA-peak output over the full operating
temperature range
• Low 500mV maximum dropout voltage at full load
• Extremely tight load and line regulation
• Tiny SOT-23-5 and MM8™ power MSOP-8 package
• Low-noise output
• Low temperature coefficient
• Current and thermal limiting
• Reversed-battery protection
• CMOS/TTL-compatible enable/shutdown control
• Near-zero shutdown current
TheMIC5216isdesignedtoprovideapeakoutputcurrentfor
startup conditions where higher inrush current is demanded.
It features a 500mA peak output rating. Continuous output
current is limited only by package and layout.

section for details.
Note 2: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
Note 3: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load regulation in the load
range from 100mA to 500mA. Changes in output voltage due to heating effects are covered by the thermal regulation specification.
Note 4: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at 1V
differential.
Note 5: Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from the supply is the sum of
the load current plus the ground pin current.

Note 7: 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

conditions that are critical to the application will give the
maximum operating conditions for the regulator circuit. For
example, if we are operating the MIC5216-3.3BM5 at room
temperature, with a minimum footprint layout, we can deter-
mine the maximum input voltage for a set output current.
Output Capacitor
An output capacitor is required between OUT and GND to
prevent oscillation. 1µF minimum is recommended. Larger
values improve the regulator’s transient response. The out-
put capacitor value may be increased without limit.

The output capacitor should have an ESR (equivalent series
resistance) of about 5Ω or less and a resonant frequency
above 1MHz. Ultralow-ESR capacitors could cause oscilla-
tion and/or underdamped transient response. Most tantalum
or aluminum electrolytic capacitors are adequate; film types
will work, but more expensive. Many aluminum electrolytics
have electrolytes that freeze at about –30°C, so solid tanta-
lums are recommended for operation below –25°C.

The thermal resistance, junction-to-ambient, for the mini-
mum footprint is 220°C/W, taken from table 1. The maximum
power dissipation number cannot be exceeded for proper
operationofthedevice. Usingtheoutputvoltageof3.3V, and
an output current of 150mA, we can determine the maximum
input voltage. Ground current, maximum of 3mA for 150mA
of output current, can be taken from the Electrical Character-
istics section of the data sheet.
At lower values of output current, less output capacitance is
needed for stability. The capacitor can be reduced to 0.47µF
for current below 10mA or 0.33µF for currents below 1mA.

Therefore, a 3.3V application at 150mA of output current can

The error flag is an open-collector output and is active (low)
when an undervoltage of approximately 5% below the nomi-
nal output voltage is detected. A pullup resistor from IN to

If an error indication is not required, FLAG may be left open

Peak Current Applications
Thermal Considerations
The MIC5216 is designed for applications where high start-
up currents are demanded from space constrained regula-
tors. This device will deliver 500mA start-up current from a
SOT-23-5 or MM8 package, allowing high power from a very
low profile device. The MIC5216 can subsequently provide
output current that is only limited by the thermal characteris-
tics of the device. You can obtain higher continuous currents
from the device with the proper design. This is easily proved
with some thermal calculations.
The MIC5216 is designed to provide 200mA of continuous
current in two very small profile packages. Maximum power
dissipationcanbecalculatedbasedontheoutputcurrentand

first step, this is done in the same manner as in the previous

Therefore, to be able to obtain a constant 500mA output
current from the 5216-5.0BM5 at room temperature, you
need extremely tight input-output voltage differential, barely
above the maximum dropout voltage for that current rating.
Applications also call for a set nominal current output with a
greater amount of current needed for short durations. This is
a tricky situation, but it is easily remedied. Calculate the
average power dissipation for each current section, then add
the two numbers giving the total power dissipation for the
regulator. For example, if the regulator is operating normally
at 50mA, but for 12.5% of the time it operates at 500mA
output, the total power dissipation of the part can be easily
determined. First, calculate the power dissipation of the
device at 50mA. We will use the MIC5216-3.3BM5 with 5V
input voltage as our example.
You can run the part from larger supply voltages if the proper
precautions are taken. Varying the duty cycle using the
enable pin can increase the power dissipation of the device
by maintaining a lower average power figure. This is ideal for
applications where high current is only needed in short
bursts. Figure 1 shows the safe operating regions for the
MIC5216-x.xBM5 at three different ambient temperatures
and at different output currents. The data used to determine
this figure assumed a minimum footprint PCB design for
minimum heat sinking. Figure 2 incorporates the same
factors as the first figure, but assumes a much better heat
sink. A 1”square copper trace on the PC board reduces the
thermal resistance of the device. This improved thermal
resistanceimprovespowerdissipationandallowsforalarger
safe operating region.
P × 50mA = (5V – 3.3V) × 50mA + 5V × 650µA
D
P × 50mA = 173mW
D
However, this is continuous power dissipation, the actual
on-time for the device at 50mA is (100%-12.5%) or 87.5% of
the time, or 87.5% duty cycle. Therefore, P must be
D
multiplied by the duty cycle to obtain the actual average
power dissipation at 50mA.
P × 50mA = 0.875 × 173mW
Figures3and4showsafeoperatingregionsfortheMIC5216-
x.xBMM, the power MSOP package part. These graphs
show three typical operating regions at different tempera-
tures. The lower the temperature, the larger the operating
region. The graphs were obtained in a similar way to the
graphs for the MIC5216-x.xBM5, taking all factors into con-
sideration and using two different board layouts, minimum
footprint and 1” square copper PC board heat sink. (For

The power dissipation at 500mA must also be calculated.
P × 500mA = (5V – 3.3V) 500mA + 5V × 20mA
D
P × 500mA = 950mW
D
This number must be multiplied by the duty cycle at which it
would be operating, 12.5%.

The total power dissipation of the regulator is less than the
maximum power dissipation of the SOT-23-5 package at
room temperature, on a minimum footprint board and there-
fore would operate properly.

Figure 5. Low-Noise Fixed Voltage Regulator
Figure 5 shows a basic MIC5216-x.xBMx fixed-voltage regu-
lator circuit. A 1µF minimum output capacitor is required for
basic fixed-voltage applications.
Multilayer boards with a ground plane, wide traces near the
pads, and large supply-bus lines will have better thermal
conductivity.
The flag output is an open-collector output and requires a
pull-up resistor to the input voltage. The flag indicates an
undervoltage condition on the output of the device.
For additional heat sink characteristics, please refer to Micrel
Application Hint 17, “Designing P.C. Board Heat Sinks”,
included in Micrel’s Databook. For a full discussion of heat
sinking and thermal effects on voltage regulators, refer to
Regulator Thermals section of Micrel’s Designing with Low-
Dropout Voltage Regulators handbook.
