† 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 of any TA (ambient temperature) is PD(max) = (TJ(max) – TA) / θJA
.
Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the reg-
ulator will go into thermal shutdown. The θJA of the MIC5255-x.xYM5 (all versions) is 235°C/W on a PC
board. See the Thermal Considerations section for further details.

Note 1: Specification for packaged product only.
2: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are
tested for load regulation in the load range from 1.0 mA to 150 mA. Changes in output voltage due to
heating effects are covered by the thermal regulation specification.
3: 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. For outputs below 2.7V, dropout voltage is the input-to-output
voltage differential with the minimum input voltage 2.7V. Minimum input operating voltage is 2.7V.
4: Ground pin current is the regulator quiescent current. The total current drawn from the supply is the sum of
the load current plus the ground pin current.

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.

without significantly slowing turn-on time. Refer to the
Typical Performance Curves section for performance
with different bypass capacitors.
4.0
4.1
APPLICATION INFORMATION
Enable Shutdown
The MIC5255 comes with an active-high enable pin
that allows the regulator to be disabled. Forcing the
enable pin low disables the regulator and sends it into
a “zero” off-mode current state. In this state, current
consumed by the regulator goes nearly to zero. Forcing
the enable pin high enables the output voltage. This
part is CMOS and the enable pin cannot be left floating;
a floating enable pin may cause an indeterminate state
on the output.
4.5
Active Shutdown
The MIC5255 also features an active shutdown clamp,
which is an N-Channel MOSFET that turns on when the
device is disabled. This allows the output capacitor and
load to discharge, de-energizing the load.
4.6
No-Load Stability
The MIC5255 will remain stable and in regulation with
no load unlike many other voltage regulators. This is
especially important in CMOS RAM keep-alive
applications.
4.2
Input Capacitor
The MIC5255 is a high performance, high bandwidth
device. Therefore, it requires a well-bypassed input
supply for optimal performance. A 1 µF capacitor is
required from the input to ground to provide stability.
Low-ESR ceramic capacitors provide optimal
performance at a minimum of space. Additional high
frequency capacitors, such as small valued NPO
dielectric type capacitors, help filter out high frequency
noise and are good practice in any RF-based circuit.
4.7
Thermal Considerations
The MIC5255 is designed to provide 150 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:
4.3
Output Capacitor
The MIC5255 requires an output capacitor for stability.
The design requires 1 µF or greater on the output to
maintain stability. The design is optimized for use with
low-ESR ceramic chip capacitors. High ESR capacitors
may cause high frequency oscillation. The maximum
recommended ESR is 300 mꢀ. The output capacitor
can be increased, but performance has been optimized
for a 1 µF ceramic output capacitor and does not
improve significantly with larger capacitance.
EQUATION 4-1:
T
JMAX – TA
-------------------------------
PDMAX
=
JA
X7R/X5R dielectric-type 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 capacitor to ensure the same
minimum capacitance over the equivalent operating
temperature range.
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 MIC5255.

A capacitor can be placed from the noise bypass pin to
ground to reduce output voltage noise. The capacitor
bypasses the internal reference. A 0.01 µF capacitor is
recommended for applications that require low-noise
outputs. The bypass capacitor can be increased,
further reducing noise and improving PSRR. Turn-on
time increases slightly with respect to bypass
capacitance. A unique quick-start circuit allows the
The actual power dissipation of the regulator circuit can
be determined using the equation:

EQUATION 4-2:
EQUATION 4-6:
PD = VIN – VOUTIOUT + VIN IGND
769mW = VIN 150mA
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
MIC5255-3.0YM5 at +50°C with a minimum footprint
layout, the maximum input voltage for a set output
current can be determined as follows:
EQUATION 4-7:
VINMAX = 5.12V
EQUATION 4-3:
Therefore, a 3.0V application at 150 mA of output
current can accept a maximum input voltage of 5.12V
in a SOT23-5 package.

= 319mW
235oC/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 3.0V and
an output current of 150 mA, the maximum input
voltage can be determined for the series of equations
between Equation 4-4 and Equation 4-7. Because this
device is CMOS and the ground current is typically
100 µA over the load range, the power dissipation
contributed by the ground current is <1% and can be
ignored for this calculation:
EQUATION 4-4:
319mW = VIN – 3.0V 150mA
EQUATION 4-5:
319mW = VIN 150mA – 450mW

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “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.
