Dual 300mA µCap LDO
in 1.6mm x 1.6mm Thin MLF®
General Description
Features
The MIC5338/9 is an advanced dual 300mA LDO ideal for
powering general purpose portable devices requiring low
output noise and excellent Power Supply Rejection Ratio
(PSRR). The MIC5338/9 provides two independently
controlled, high performance, 300mA LDOs in a tiny
1.6mm x 1.6mm Thin MLF® package.
• 2.5V to 5.5V input voltage range
• Two 300mA outputs
• High output accuracy – 2%
• Low quiescent current – 70µA total
• Stable with ceramic output capacitors
• Independent enable pins
• Low dropout voltage – 220mV at 300mA
• Low output noise
• Thermal shutdown protection
• Current limit protection
The MIC5338/9 provides two low noise outputs with fast
transient response. Additionally the MIC5338/9 provides
low quiescent current operation, using only 70μA with both
outputs enabled. The MIC5339 also incorporates an active
discharge feature that pulls down the output of the
regulator when the part is disabled.
• Output discharge circuit – MIC5339
• 6-pin 1.6mm x 1.6mm Thin MLF® package
The MIC5338/9 is available in fixed output voltages in a
lead-free (RoHS compliant) 6-pin 1.6mm x 1.6mm Thin
MLF® leadless package.

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.

MIC5338/9
Application Information
Enable/Shutdown
MIC5338/9 is a dual 300mA LDO. The MIC5339
includes an auto-discharge circuit for each LDO output
that is activated when the output is disabled. The
MIC5338/9 regulator is fully protected from damage due
to fault conditions through linear current limiting and
thermal shutdown.
The MIC5338/9 comes with two active high enable pins
that allow each regulator to be disabled independently.
Forcing the enable pin low disables the regulator and
sends it into an off mode current state drawing virtually
zero current. When disabled, the MIC5339 switches an
internal 30Ω load on the regulator output to discharge
the external capacitor.
Input Capacitor
Forcing the enable pin high enables the output voltage.
The active high enable pin uses CMOS technology and
cannot be left floating. A floating enable pin may cause
an indeterminate state on the output.
The MIC5338/9 is a high performance, high bandwidth
device. An input capacitor of 1µF from the input pin to
ground is required to provide stability. Low ESR ceramic
capacitors provide optimal performance in small board
area. 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.
Thermal Considerations
The MIC5338/9 is designed to provide two 300mA
continuous current outputs in a very small package.
Maximum operating temperature can be calculated
based on the output currents and the voltage drop
across the part. For example, if the input voltage is 3.6V,
VOUT1 = 3.3V, VOUT2 = 2.8V and each with an output
current = 300mA. The actual power dissipation of the
regulator circuit can be determined using the equation:
Output Capacitor
The MIC5338/9 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 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.
PD = (VIN – VOUT1) IOUT1 + (VIN – VOUT2) I OUT2 + VIN IGND
Because this is CMOS device and the ground current is
typically <100µA over the load range, the power
dissipation contributed by the ground current is < 1%
which can be ignored for this calculation.
PD = (3.6V – 3.3V) × 300mA + (3.6V – 2.8V) × 300mA
PD = 0.33W
X7R and X5R dielectric ceramic capacitors are
recommended
because
of
their
temperature
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:
performance. X7R 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) = 125°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
92.4°C/W.
No Load Stability
Unlike many other voltage regulators, the MIC5338/9 will
remain stable and in regulation with no load.
The maximum power dissipation must not be exceeded
for proper operation.

MIC5338/9
For example, when operating a 3.3V/2.8V application
with an input voltage of 3.6V and 300mA at each output
with a minimum footprint layout, the maximum ambient
operating temperature TA can be determined as follows:
Therefore, a MIC5338-SMYMT application with 300mA
at each output current can accept an ambient operating
temperature of 94.5°C in a 1.6mm x 1.6mm Thin 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 Regulators handbook. This
information can be found on Micrel's website at:
0.33W = (125°C – TA)/(92.4°C/W)
