MIC5207
180mA Low-Noise LDO Regulator
General Description
Features
TheMIC5207isanefficientlinearvoltageregulatorwithultra-
low-noise output, very low dropout voltage (typically 17mV at
light loads and 165mV at 150mA), and very low ground
current (720µA at 100mA output). The MIC5207 offers better
than 3% initial accuracy.
• Ultra-low-noise output
• High output voltage accuracy
• Guaranteed 180mA output
• Low quiescent current
• Low dropout voltage
• Extremely tight load and line regulation
• Very low temperature coefficient
• Current and thermal limiting
• Reverse-battery protection
• “Zero” off-mode current
Designedespeciallyforhand-held,battery-powereddevices,
the MIC5207 includes a CMOS or TTL compatible enable/
shutdown control input. When shutdown, power consump-
tion drops nearly to zero.
Key MIC5207 features include a reference bypass pin to
improve its already low-noise performance, reversed-battery
protection, current limiting, and overtemperature shutdown.
• Logic-controlled electronic enable
Applications
The MIC5207 is available in fixed and adjustable output
voltage versions in a small SOT-23-5 package. Contact

(M5) is 235°C/W and the TO-92 (Z) is 180°C/W (0.4" leads) or 160°C/W (0.25" leads) soldered to a PC board. See “Thermal Considerations.”
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 180mA. Changes in output voltage due to heating effects are covered by the thermal regulation specification.
Note 6: Dropout voltage is 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 180mA load pulse at V = 16V for t = 10ms.

The junction-to-ambient thermal resistance for the minimum

used (see Figure 2). 2.2µF minimum is recommended when
is 470pF (see Figure 1). Larger values improve the
regulator’s transient response. The output capacitor value

may be increased without limit.
The output capacitor should have an ESR (effective series
resistance) of about 5Ω or less and a resonant frequency
above 1MHz. Ultra-low-ESR capacitors can cause a low
amplitude oscillation on the output and/or underdamped
transient response. Most tantalum or aluminum electrolytic
capacitors are adequate; film types will work, but are more
expensive. Since many aluminum electrolytics have electro-
lytes that freeze at about –30°C, solid tantalums are recom-
mended for operation below –25°C.

Therefore, a 3.3V application at 150mA of output current can
accept a maximum input voltage of 6V in a SOT-23-5 pack-
age. For a full discussion of heat sinking and thermal effects
on voltage regulators, refer to the Regulator Thermals sec-
tion of Micrel’s Designing with Low-Dropout Voltage Regula-
tors handbook.
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.
No-Load Stability
Low-Voltage Operation
TheMIC5207willremainstableandinregulationwithnoload
(other than the internal voltage divider) unlike many other
voltage regulators. This is especially important in CMOS
RAM keep-alive applications.
The MIC5207-1.8 and MIC5207-2.5 require special consid-
eration when used in voltage-sensitive systems. They may
momentarily overshoot their nominal output voltages unless
appropriate output and bypass capacitor values are chosen.
Thermal Considerations
During regulator power up, the pass transistor is fully satu-
rated for a short time, while the error amplifier and voltage
reference are being powered up more slowly from the output
The MIC5207 is designed to provide 180mA of continuous
current in a very small package. Maximum power dissipation

(see “Block Diagram”). Selecting larger output and bypass
capacitors allows additional time for the error amplifier and
reference to turn on and prevent overshoot.
Adjustable Regulator Applications
The MIC5207BM5 can be adjusted to a specific output
voltage by using two external resistors (figure 3). The resis-
tors set the output voltage based on the following equation:
To ensure that no overshoot is present when starting up into
a light load (100µA), use a 4.7µF output capacitance and
470pF bypass capacitance. This slows the turn-on enough to
allow the regulator to react and keep the output voltage from
exceeding its nominal value. At heavier loads, use a 10µF
output capacitance and 470pF bypass capacitance. Lower
values of output and bypass capacitance can be used,
depending on the sensitivity of the system.

This equation is correct due to the configuration of the
bandgap reference. The bandgap voltage is relative to the
output, as seen in the block diagram. Traditional regulators
normally have the reference voltage relative to ground;
therefore, their equations are different from the equation for
the MIC5207BM5.
Applications that can withstand some overshoot on the
output of the regulator can reduce the output capacitor and/
orreduceoreliminatethebypasscapacitor. Applicationsthat
are not sensitive to overshoot due to power-on reset delays
can use normal output and bypass capacitor configurations.
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.
Please note the junction temperature range of the regulator
at 1.8V output (fixed and adjustable) is 0˚C to +125˚C.
