devices, the MIC5207 includes a CMOS or TTL
compatible enable/shutdown control input. When in
shutdown, power consumption drops nearly to zero.
Key MIC5207 features include a reference bypass pin
to improve its already low-noise performance,
reversed-battery protection, current limiting, and over
temperature shutdown.
The MIC5207 is available in fixed and adjustable output
voltage versions in a small SOT-23-5 package. Contact
Microchip for details.
For low-dropout regulators that are stable with ceramic
output capacitors, see the µCap MIC5245/6/7 family.

† Notice: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
This is a stress rating only and functional operation of the device at those or any other conditions above those indicated
in the operational sections of this specification is not intended. Exposure to maximum rating conditions for extended
periods may affect device reliability.
‡ Notice: The device is not guaranteed to function outside its operating ratings.
Note 1: The maximum allowable power dissipation at any TA (ambient temperature) is PD(max) = (TJ(max) – TA) / θJA.
Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. The θJA of the SOT-23-5 (M5) is 235°C/W soldered on a PC board (see
“Thermal Considerations” for further details).

Specification for packaged product only.
Output voltage temperature coefficient is defined as the worst-case voltage change divided by the total
temperature range.
Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are
tested for load regulation in the load range from 0.1 mA to 180 mA. Changes in output voltage due to heating effects are covered by the thermal regulation specification.
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.
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.
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 180 mA load pulse at VIN =
16V for t = 10 ms.

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.

APPLICATIONS INFORMATION
4.1
Enable/Shutdown
Forcing EN (enable/shutdown) high (> 2V) enables the
regulator. EN is compatible with CMOS logic gates.
If the enable/shutdown feature is not required, connect
EN (pin 3) to IN (supply input, pin 1). See Figure 4-1.
4.2
Input Capacitor
A 1 µF capacitor should be placed from IN to GND if
there is more than 10 inches of wire between the input
and the AC filter capacitor or if a battery is used as the
input.
4.3
Reference Bypass Capacitor
Reference bypass (BYP) is connected to the internal
voltage reference. A 470 pF capacitor (CBYP)
connected from BYP to GND quiets this reference,
providing a significant reduction in output noise. CBYP
reduces the regulator phase margin; when using CBYP,
output capacitors of 2.2 µF or greater are generally
required to maintain stability.
The start-up speed of the MIC5207 is inversely
proportional to the size of the reference bypass
capacitor. Applications requiring a slow ramp-up of
output voltage should consider larger values of CBYP.
Likewise, if rapid turn-on is necessary, consider
omitting CBYP.
If output noise is not a major concern, omit CBYP and
leave BYP open.
4.4
Output Capacitor
An output capacitor is required between OUT and GND
to prevent oscillation. The minimum size of the output
capacitor is dependent upon whether a reference
bypass capacitor is used. 1.0 µF minimum is
recommended when CBYP is not used (see Figure 4-2).
2.2 µF minimum is recommended when CBYP is 470 pF
(see Figure 4-1). Larger values improve the regulator’s
transient response. The output capacitor value may be
increased without limit.
The output capacitor should have an ESR (effective
series resistance) of about 5Ω or less and a resonant
frequency above 1 MHz. Ultra-low-ESR (ceramic)
capacitors can cause a low amplitude oscillation on the
output and/or under-damped transient response. Most
tantalum or aluminum electrolytic capacitors are
adequate; film types will work, but are more expensive.
Since many aluminum electrolytics have electrolytes
that freeze at about –30°C, solid tantalums are
recommended for operation below –25°C.
2017 - 2022 Microchip Technology Inc. and its subsidiaries
At lower values of output current, less output
capacitance is required for output stability. The
capacitor can be reduced to 0.47 µF for current below
10 mA or 0.33 µF for currents below 1 mA.
4.5
No-Load Stability
The MIC5207 will remain stable and in regulation with
no load (other than the internal voltage divider) unlike
many other voltage regulators. This is especially
important in CMOS RAM keep-alive applications.
4.6
Thermal Considerations
The MIC5207 is designed to provide 180 mA of
continuous current in a very small package. Maximum
power dissipation can be calculated based on the
output current and the voltage drop across the part. To
determine the maximum power dissipation of the
package, use the junction-to-ambient thermal
resistance of the device and the following basic
equation shown in Equation 4-1:
EQUATION 4-1:
T J MAX – T A
P D MAX = ----------------------------------- JA
TJ(MAX) is the maximum junction temperature of the
die, +125°C, and TA is the ambient operating
temperature. θJA is layout dependent; Table 4-1 shows
examples of junction-to-ambient thermal resistance for
the MIC5207.
TABLE 4-1:

RESISTANCE
θJA Rec.
Min. Footprint
θJA 1” Square
Copper Clad
θJ/C
235°C/W
170°C/W
130°C/W
The actual power dissipation of the regulator circuit can
be determined using Equation 4-2:
EQUATION 4-2:
P D = V IN – V OUT I OUT + V IN I GND
Substituting PD(MAX) for PD and solving for the
operating conditions that are critical to the application
will give the maximum operating conditions for the
regulator circuit. For example, when operating the
DS20005719C-page 11
MIC5207
MIC5207-3.3YM5 at room temperature with a minimum
footprint layout, the maximum input voltage for a set
output current can be determined with Equation 4-3:
EQUATION 4-3:
o
o
125 C – 25 C
P D MAX = ---------------------------------- = 425mW
o
235 C/W
The junction-to-ambient thermal resistance for the
minimum footprint is 235°C/W, from Table 4-1. The
maximum power dissipation must not be exceeded for
proper operation. Using the output voltage of 3.3V and
an output current of 150 mA, the maximum input
voltage can be determined. From the Electrical
Characteristics table, the maximum ground current for
150 mA output current is 3000 µA or 3 mA.
EQUATION 4-4:
425mW = V IN – 3.3V 150mA + V IN 3mA
Where:
EQUATION 4-5:
425mW = V IN 150mA – 495mW + V IN 3mA
Therefore, a 3.3V application at 150 mA of output
current can accept a maximum input voltage of 6V in a
SOT-23-5 package. For a full discussion of heat sinking
and thermal effects on voltage regulators, refer to the
Regulator Thermals section of Microchip’s Designing
with Low-Dropout Voltage Regulators handbook.
4.7
Low-Voltage Operation
The MIC5207-1.8 and MIC5207-2.5 require special
consideration when used in voltage-sensitive systems.
They may momentarily overshoot their nominal output
voltages unless appropriate output and bypass
capacitor values are chosen.
During regulator power up, the pass transistor is fully
saturated for a short time, while the error amplifier and
voltage reference are being powered up more slowly
from the output (see Functional Diagrams). Selecting
larger output and bypass capacitors allows additional
time for the error amplifier and reference to turn on and
prevent overshoot.
To ensure that no overshoot is present when starting up
into a light load (100 µA), use a 4.7 µF output
capacitance and 470 pF bypass capacitance. This
slows the turn-on enough to allow the regulator to react
and keep the output voltage from exceeding its nominal
value. At heavier loads, use a 10 µF output
capacitance and 470 pF bypass capacitance. Lower
values of output and bypass capacitance can be used,
depending on the sensitivity of the system.
Applications that can withstand some overshoot on the
output of the regulator can reduce the output capacitor
and/or reduce or eliminate the bypass capacitor.
Applications that are not sensitive to overshoot due to
power-on reset delays can use normal output and
bypass capacitor configurations.
Please note the junction temperature range of the
regulator with an output less than 2.5V fixed and
adjustable is 0°C to +125°C.

When used in dual-supply systems where the regulator
load is returned to a negative supply, the output voltage
must be diode clamped to ground.

Adjustable Regulator Applications
The MIC5207YM5 can be adjusted to a specific output
voltage by using two external resistors (Figure 4-3).
The resistors set the output voltage based on
Equation 4-8:

Figure 4-4 shows the MIC5207-3.3YM5 in a USB

This equation is correct due to the configuration of the
bandgap reference. The bandgap voltage is relative to
the output, as seen in the Functional Diagrams.
Traditional regulators normally have the reference
voltage relative to ground; therefore, their equations
are different from the equation for the MIC5207YM5.
Resistor values are not critical because ADJ (adjust)
has a high input impedance, but for best results use
resistors of 470 kΩ or less. A capacitor from ADJ to
ground provides greatly improved noise performance.
