MIC5206
150mA Low-Noise LDO Regulator
General Description
Features
The MIC5206 is an efficient linear voltage regulator with very
low dropout voltage (typically 17mV at light loads and 165mV
at 150mA), and very low ground current (600µA at 100mA
output), with better than 1% initial accuracy. It has a logic
compatible enable/shutdown control input and an internal
undervoltage monitor.
• Error flag indicates undervoltage fault
• High output voltage accuracy
• Guaranteed 150mA output
• Ultra-low-noise output (8-lead versions)
• Low quiescent current
• Low dropout voltage
• Extremely tight load and line regulation
• Very low temperature coefficient
• Current and thermal limiting
• Reversed-battery protection
• “Zero” off-mode current
Designedespeciallyforhand-held,battery-powereddevices,
the MIC5206 can be switched by a CMOS or TTL compatible
logic signal. When disabled, power consumption drops
nearly to zero. Dropout ground current is minimized to
prolong battery life.
• Logic-controlled electronic enable
Key features include an undervoltage monitor with an error
flagoutput, areferencebypasspintoimproveitsalreadylow-
noise performance (8-lead versions only), reversed-battery
protection, current limiting, and overtemperature shutdown.
Applications
• Cellular telephones
The MIC5206 is available in several fixed voltages in a tiny
SOT-23-5package.Itfeaturesapinout,similartotheLP2980,
but has significantly better performance. Fixed and adjust-
able output voltage versions, featuring the reference bypass
option, are available in the 8-lead Micrel Mini 8™ 8-lead
MSOP (micro small-outline package).
• Laptop, notebook, and palmtop computers
• Battery-powered equipment
• PCMCIA V and V regulation/switching
CC
PP
• Consumer/personal electronics
• SMPS post-regulator/dc-to-dc modules
• High-efficiency linear power supplies
For low-dropout regulators that are stable with ceramic
output capacitors, see the µCap MIC5245/6/7 family.

MIC5205-x.xBM5 (all versions) is 220°C/W, and the MIC5206-x.xBMM (all versions) is 200°C/W, mounted on a PC board (see “Thermal
Considerations” for further details).
Note 4: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
Note 5: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load regulation in the load
range from 0.1mA to 150mA. Changes in output voltage due to heating effects are covered by the thermal regulation specification.
Note 6: 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.
Note 7: 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.
Note 8: 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 150mA load pulse at V = 16V for t = 10ms.

Note 9: The error flag comparator includes 3% hysteresis.

If an error indication is not required, FLAG may be left open
and the pullup resistor may be omitted.
Applications Information
Enable/Shutdown
Enable Pin Ramp and the Error Flag
Forcing EN (enable/shutdown) high (> 2V) enables the regu-
lator. EN is compatible with CMOS logic gates.
To prevent indeterminate behavior on the error flag during
power down of the device, ensure that the fall time of the
enable pin signal, from logic high to logic low, is faster than
100µs.
If the enable/shutdown feature is not required, connect EN
(enable) to IN (supply input). Refer to the text with Figures 1a
and 2.

Ultra-Low-Noise Application
The output capacitor should have an ESR (effective series
resistance) of about 5Ω or less and a resonant frequency
above 1MHz. Most tantalum or aluminum electrolytic capaci-
tors are adequate; film types will work, but are more expen-
sive. Since many aluminum electrolytics have electrolytes
that freeze at about –30°C, solid tantalums are recom-
mended for operation below –25°C.

At lower values of output current, less output capacitance is
required for output stability. The capacitor can be reduced to
0.47µF for current below 10mA or 0.33µF for currents below
1mA.

Figure 2 includes a 470pF capacitor for low-noise operation

tion where enable/shutdown is not required. The error flag is

Adjustable Regulator Applications
Error Flag Ouput
Figure 3 shows the MIC5206BMM adjustable output voltage
configuration. Two resistors set the output voltage. The
formula for output voltage is:
The error flag is an open-collector output and is active (low)
when an undervoltage of approximately 5% below the nomi-
nal output voltage is detected. A pullup resistor from IN to
FLAG is shown in all schematics.

Resistor values are not critical because ADJ (adjust) has a
high input impedance, but for best results use resistors of
470kΩ or less. A capacitor from ADJ to ground provides
greatly improved noise performance.

The MIC5206-xxBMM (8-lead MSOP) has a thermal resis-
tance of 200°C/W when mounted on a FR4 board with
minimum trace widths and no ground plane.

Nominal Power Dissipation and Die Temperature
The MIC5206-x.xBM5 at a 25°C ambient temperature will
operate reliably at over 450mW power dissipation when
mounted in the “worst case” manner described above. At an
ambient temperature of 40°C, the device may safely dissi-
pate over 380mW. These power levels are equivalent to a die
temperature of 125°C, the maximum operating junction tem-
perature for the MIC5206.
Figure 3 also includes a 470pF capacitor for lowest-noise
operation and shows EN (pin 7) connected to IN (pin 8) for an
application where enable/shutdown is not required. C

For additional heat sink characteristics, please refer to Micrel
Application Hint 17, “Calculating P.C. Board Heat Sink Area
For Surface Mount Packages”.
The MIC5206-x.xBM5 (5-lead SOT-23 package) has the
following thermal characteristics when mounted on a single
layer copper-clad printed circuit board.
Multilayerboardshavingagroundplane,widetracesnearthe
pads, and large supply bus lines provide better thermal
conductivity.
