Micrel MIC5377YMT High performance low dropout 150ma ldo Datasheet

MIC5375/6/7/8
High Performance Low Dropout 150mA LDO
General Description
Features
The MIC5375/6/7/8 is an advanced general purpose linear
regulator offering low dropout in an ultra small package.
The MIC5375/6 provides fixed output voltage in a 1mm x
1mm Thin MLF® package while the MIC5377/8 provides
adjustable output voltage in a 1.2mm x 1.2mm Thin MLF®
package. When the MIC5376/8 is disabled an internal
resistive load is automatically applied to the output to
discharge the output capacitor. The MIC5375/6/7/8 is
capable of sourcing 150mA output current with low dropout
making it an ideal solution for any portable electronic
application.
Ideal for battery powered applications, the MIC5375/6/7/8
offers 2% initial accuracy, low dropout voltage (120mV at
150mA), and ground current (typically 29µA). The
MIC5375/6/7/8 can also be put into a zero-off-mode
current state, drawing virtually no current when disabled.
The MIC5375/6 is available in lead-free (RoHS compliant)
1mm x 1mm Thin MLF® and SC-70-5. The MIC5377/8 is
available in lead-free (RoHS compliant) 1.2mm x 1.2mm
Thin MLF® and SC-70-5.
The MIC5375/6/7/8 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, 1.5kΩ in series with 100pF.
5. Specification for packaged product only.
6. Regulation is measured at constant junction temperature using low duty cycle pulse testing.
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.

Application Information
Enable/Shutdown
The MIC5375/6/7/8 is provided 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.
MIC5375/6/7/8 is Low noise 150mA LDO. The
MIC5376/8 includes an auto-discharge circuit that is
switched on when the regulator is disabled through the
enable pin. The MIC5375/6/7/8 regulator is protected
from damage due to fault conditions, offering linear
current limiting and thermal shutdown.
Input Capacitor
The MIC5375/6/7/8 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.
Adjustable Regulator Design
The MIC5377/8 adjustable version allows setting the
output voltage down to 1V with the use of two external
feedback resistors.

Output Capacitor
For output voltages ≥ 2.5V, the MIC5375/6/7/8 requires
a minimum 1µF output capacitor. For output voltages
below 2.5V a 2.2µF minimum output capacitor is
required. 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 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.

Thermal Considerations
The MIC5375/6/7/8 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.
PD = (3.6V – 2.8V) × 150mA
PD = 0.12W
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:
No-Load Stability
Unlike many other voltage regulators, the MIC5375/6/7/8
will remain stable and in regulation with no load. This is
especially important in CMOS RAM keep-alive
applications.
⎛ TJ(max) − TA
PD(max) = ⎜⎜
θ JA
⎝
⎞
⎟
⎟
⎠
TJ(max) = 125°C, the maximum junction temperature of the
die, θJA thermal resistance = 250°C/W for the YMT
package and 256.5°C/W for the SC-70-5 package.

MIC5375/6/7/8
Therefore the maximum ambient operating temperature
of 95°C is allowed in a 1mm x 1mm TMLF® 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
Regulators handbook. This information can be found on
Micrel's website at:
http://www.micrel.com/_PDF/other/LDOBk_ds.pdf
Substituting PD for PD(max) and solving for the ambient
operating temperature will give the maximum operating
conditions for the regulator circuit. The junction-toambient 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 MIC5375-2.8YMT 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:
0.12W = (125°C – TA)/(250°C/W)
TA = 95°C
