MIC5207
180mA Low-Noise LDO Regulator
General Description
Features
The MIC5207 is an efficient linear voltage regulator with ultralow-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.

Designed especially for hand-held, battery-powered devices,
the MIC5207 includes a CMOS or TTL compatible enable/
shutdown control input. When shutdown, power consumption 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.
The MIC5207 is available in fixed and adjustable output
voltage versions in a small SOT-23-5 package. Contact

Note 1.
Exceeding the absolute maximum rating may damage the device.
Note 2.
The device is not guaranteed to function outside its operating rating.
Note 3:
The maximum allowable power dissipation at any TA (ambient temperature) is PD(max) = (TJ(max) – TA) ÷ θJA. Exceeding the maximum
allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. The θJA of the SOT-23-5
(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 VIN = 16V for t = 10ms.

drop across the part. To determine the maximum power
dissipation of the package, use the junction-to-ambient thermal resistance of the device and the following basic equation:
Applications Information
Enable/Shutdown
Forcing EN (enable/shutdown) high (> 2V) enables the regulator. EN is compatible with CMOS logic gates.
If the enable/shutdown feature is not required, connect EN
(pin 3) to IN (supply input, pin 1). See Figure 1.
Input Capacitor
PD(max) =
θ JA
TJ(max) is the maximum junction temperature of the die,
125°C, and TA is the ambient operating temperature. θJA is
layout dependent; Table 1 shows examples of junction-toambient thermal resistance for the MIC5207.
A 1µF capacitor should be placed from IN to GND if there is
more than 10 inches of wire between the input and the ac filter
capacitor or if a battery is used as the input.
Reference Bypass Capacitor
Package
BYP (reference bypass) is connected to the internal voltage
reference. A 470pF capacitor (CBYP) connected from BYP to
GND quiets this reference, providing a significant reduction in
output noise. CBYP reduces the regulator phase margin;
when using CBYP, output capacitors of 2.2µF or greater are
generally required to maintain stability.
The start-up speed of the MIC5207 is inversely proportional
to the size of the reference bypass capacitor. Applications
requiring a slow ramp-up of output voltage should consider
larger values of CBYP. Likewise, if rapid turn-on is necessary,
consider omitting CBYP.
If output noise is not a major concern, omit CBYP and leave
BYP open.

Table 1. SOT-23-5 Thermal Resistance
The actual power dissipation of the regulator circuit can be
determined using the equation:
PD = (VIN – VOUT) IOUT + VIN IGND
Substituting PD(max) for PD and solving for the operating
conditions that are critical to the application will give the
maximum operating conditions for the regulator circuit. For
example, when operating the MIC5207-3.3BM5 at room
temperature with a minimum footprint layout, the maximum
input voltage for a set output current can be determined as
follows:
Output Capacitor
An output capacitor is required between OUT and GND to
prevent oscillation. The minimum size of the output capacitor
is dependent upon whether a reference bypass capacitor is
used. 1.0µF minimum is recommended when CBYP is not
used (see Figure 2). 2.2µF minimum is recommended when
CBYP is 470pF (see Figure 1). Larger values improve the
regulator’s transient response. The output capacitor value
may be increased without limit.
PD(max) =
125˚C − 25˚C
235
PD(max) = 425mW
The junction-to-ambient thermal resistance for the minimum
footprint is 220°C/W, from Table 1. The maximum power
dissipation must not be exceeded for proper operation. Using
the output voltage of 3.3V and an output current of 150mA,
the maximum input voltage can be determined. From the
Electrical Characteristics table, the maximum ground current
for 150mA output current is 3000µA or 3mA.
455mW = (VIN – 3.3V) 150mA + VIN ·3mA
455mW = VIN ·150mA – 495mW + VIN ·3mA
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 electrolytes that freeze at about –30°C, solid tantalums are recommended 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.
No-Load Stability
920mW = VIN ·153mA
VIN(max) = 6.01V
Therefore, a 3.3V application at 150mA of output current can
accept a maximum input voltage of 6V in a SOT-23-5 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.
Low-Voltage Operation
The MIC5207-1.8 and MIC5207-2.5 require special consideration when used in voltage-sensitive systems. They may
momentarily overshoot their nominal output voltages unless
appropriate output and bypass capacitor values are chosen.
The MIC5207 will remain stable and in regulation with no load
(other than the internal voltage divider) unlike many other
voltage regulators. This is especially important in CMOS
RAM keep-alive applications.
Thermal Considerations
During regulator power up, the pass transistor is fully saturated 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
can be calculated based on the output current and the voltage

Adjustable Regulator Applications
The MIC5207BM5 can be adjusted to a specific output
voltage by using two external resistors (figure 3). The resistors set the output voltage based on the following equation:
(see “Block Diagram”). Selecting larger output and bypass
capacitors allows additional time for the error amplifier and
reference to turn on and prevent overshoot.
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.
 R2 
VOUT = VREF 1 +
 , VREF = 1.242V
 R1
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.
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.
Applications that can withstand some overshoot on the
output of the regulator can reduce the output capacitor and/
or reduce or eliminate the bypass capacitor. Applications that
are not sensitive to overshoot due to power-on reset delays
can use normal output and bypass capacitor configurations.
Please note the junction temperature range of the regulator
at 1.8V output (fixed and adjustable) is 0˚C to +125˚C.

Figure 3 includes the optional 470pF noise bypass capacitor
from ADJ to GND to reduce output noise.
Figure 1 includes a 470pF capacitor for ultra-low-noise operation and shows EN (pin 3) connected to IN (pin 1) for an
application where enable/shutdown is not required. COUT =
2.2µF minimum.
Dual-Supply Operation
When used in dual-supply systems where the regulator load
is returned to a negative supply, the output voltage must be
diode clamped to ground.
