General Description
The MIC5365/6 is an advanced general purpose linear
regulator offering high power supply rejection (PSRR) in
an ultra-small 1mm x 1mm package. The MIC5366
includes an auto-discharge feature that is activated when
the enable pin is low. The MIC5365/6 is capable of
sourcing 150mA output current and offers high PSRR
making it an ideal solution for any portable electronic
application.
Ideal for battery-powered applications, the MIC5365/6
offers 2% initial accuracy, low dropout voltage (155mV @
150mA), and low ground current (typically 29µA). The
MIC5365/6 can also be put into a zero-off-mode current
state, drawing virtually no current when disabled.
The MIC5365/6 is available in several advanced packages
including a lead-free (RoHS-compliant) 1mm x 1mm Thin
MLF® occupying only 1mm2 of PCB area, a 75% reduction
in board area compared to SC-70 and 2mm x 2mm MLF®
packages. It is also available in a thin SOT23-5 package.
The MIC5365/6 has an operating junction temperature
range of –40°C to 125°C.

Notes:
1. Exceeding the absolute maximum rating may damage the device.
2. The device is not guaranteed to function outside its operating rating.
3. 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 regulator will go into thermal shutdown.
4. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
5. Specification for packaged product only.
6. Regulation is measured at constant junction temperature using low duty cycle pulse testing, changes in output voltage due to heating effects are
covered by the thermal regulation specification.
7. 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 2.5V, dropout voltage is the input-to-output differential with the minimum input voltage 2.5V.
8. 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.

Functional Characteristics
Micrel, Inc. MIC5365/6
June 2012 9 M9999-062012-C
Application Information
MIC5365 and MIC5366 are Low noise 150mA LDOs.
The MIC5366 includes an auto-discharge circuit that is
switched on when the regulator is disabled through the
Enable pin. The MIC5365/6 regulator is fully protected
from damage due to fault conditions, offering linear
current limiting and thermal shutdown.
Input Capacitor
The MIC5365/6 is a high-performance, high bandwidth
device. An input capacitor of 1µF 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. X5R or X7R dielectrics are
recommended for the input capacitor. Y5V dielectrics
lose most of their capacitance over temperature and are
therefore, not recommended.
Output Capacitor
The MIC5365/6 requires an output capacitor of 1µF or
greater to maintain stability. The design is optimized for
use with low-ESR ceramic chip capacitors. High ESR
capacitors are not recommended because they may
cause high frequency oscillation. The output capacitor
can be increased, but performance has been optimized
for a 1µF ceramic output capacitor and does not improve
significantly with larger capacitance.
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.
No-Load Stability
Unlike many other voltage regulators, the MIC5365/6 will
remain stable and in regulation with no load. This is
especially important in CMOS RAM keep-alive
applications.
Enable/Shutdown
The MIC5365/6 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. The
active-high enable pin uses CMOS technology and the
enable pin cannot be left floating; a floating enable pin
may cause an indeterminate state on the output.
Thermal Considerations
The MIC5365/6 is designed to provide 150mA of
continuous current in a very small package. Maximum
ambient operating temperature can be calculated based
on the output current and the voltage drop across the
part. For example if the input voltage is 3.6V, the output
voltage is 2.8V, and the output current = 150mA. The
actual power dissipation of the regulator circuit can be
determined using the equation:
PD = (VIN – VOUT1) I OUT + VIN IGND
Because this device is CMOS and the ground current is
typically <100µA over the load range, the power
dissipation contributed by the ground current is < 1% and
can be ignored for this calculation:
P
D = (3.6V – 2.8V) × 150mA
P
D = 0.120W
To determine the maximum ambient operating
temperature of the package, use the junction-to-ambient
thermal resistance of the device and the following basic
equation:
=
JA
AJ(max)
D(MAX)
TT
P
TJ(max) = 125°C, the maximum junction temperature of the
die, JA thermal resistance = 250°C/W for the YMT
package, 256.5°C/W for the SC-70-5 package and
235°C/W for the MIC5365/6 in the TSOT23-5 package .
Micrel, Inc. MIC5365/6
June 2012 10 M9999-062012-C
Substituting PD for PD(max) and solving for the ambient
operating temperature will give the maximum operating
conditions for the regulator circuit. The junction-to-
ambient thermal resistance for the minimum footprint is
250°C/W.
The maximum power dissipation must not be exceeded
for proper operation.
For example, when operating the MIC5365-2.8YMT at
an input voltage of 3.6V and 150mA load with a
minimum footprint layout, the maximum ambient
operating temperature TA can be determined as follows:
0.120W = (125°C – TA)/(250°C/W)
T
A = 95°C
Therefore the maximum ambient operating temperature
of 95°C is allowed in a 1mm x 1mm MLF® package. For
a full discussion of heat sinking and thermal effects on
voltage regulators, refer to the “Regulator Thermals”
section of Micrel’s Designing with Low-Dropout Voltage
