The MIC5205 is an efficient linear voltage regulator
with ultra low-noise output, very low dropout voltage
(typically 17 mV at light loads and 165 mV at 150 mA),
and very low ground current (600 µA at 100 mA
output). The MIC5205 offers better than 1% initial
accuracy.

High-Efficiency Linear Power Supplies
Designed especially for hand-held, battery-powered
devices, the MIC5205 includes a CMOS or TTL
compatible enable/shutdown control input. When shut
down, power consumption drops nearly to zero.
Regulator ground current increases only slightly in
dropout, further prolonging battery life.
Key MIC5205 features include a reference bypass pin
to improve its already excellent low-noise performance,
reversed-battery protection, current limiting, and
overtemperature shutdown.
The MIC5205 is available in fixed and adjustable output
voltage versions in a small SOT-23-5 package.
For low-dropout regulators that are stable with ceramic
output capacitors, see the µCap MIC5245/6/7 family.

† Notice: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
This is a stress rating only and functional operation of the device at those or any other conditions above those indicated
in the operational sections of this specification is not intended. Exposure to maximum rating conditions for extended
periods may affect device reliability.
‡ Notice: The device is not guaranteed to function outside its operating ratings.
Note 1: The maximum allowable power dissipation at any TA (ambient temperature) is PD(max) = (TJ(max) – TA)/JA.
Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. The JA of the MIC5205-xxYM5 (all versions) is 220°C/W mounted on
a PC board.

Output voltage temperature coefficient is defined as the worst case voltage change divided by the total
temperature range.
Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are
tested for load regulation in the load range from 0.1 mA to 150 mA. Changes in output voltage due to heating effects are covered by the thermal regulation specification.
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.
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.
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 150 mA load pulse at VIN =
16V for t = 10 ms.

Note 1:
2:
The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable
junction temperature and the thermal resistance from junction to air (i.e., TA, TJ, JA). Exceeding the
maximum allowable power dissipation will cause the device operating junction temperature to exceed the
maximum +125°C rating. Sustained junction temperatures above +125°C can impact the device reliability.
The maximum allowable power dissipation at any TA (ambient temperature) is PD(max) = (TJ(max) – TA)/JA.
Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. The JA of the MIC5205-xxYM5 (all versions) is 220°C/W mounted on
a PC board.

APPLICATION INFORMATION
4.1
Enable/Shutdown
Forcing EN (enable/shutdown) high (greater than 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 4-1.
4.2
Input Capacitor
A 1 µF capacitor should be placed from IN to GND if
there are more than 10 inches of wire between the
input and the AC filter capacitor or if a battery is used
as the input.
4.3
Reference Bypass Capacitor
BYP (reference bypass) is connected to the internal
voltage reference. A 470 pF 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 2.2 µF or greater are generally
required to maintain stability.
The start-up speed of the MIC5205 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.
4.4
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. 1.0 µF minimum is
recommended when CBYP is not used (see Figure 4-2).
2.2 µF minimum is recommended when CBYP is 470 pF
(see Figure 4-1). 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 1 MHz. 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. Because
many aluminum electrolytics have electrolytes that
freeze at about –30°C, solid tantalums are
recommended for operation below –25°C.
DS20005785A-page 10
At lower values of output current, less output
capacitance is required for output stability. The
capacitor can be reduced to 0.47 µF for current below
10 mA or 0.33 µF for currents below 1 mA.
4.5
No-Load Stability
The MIC5205 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.
4.6
Thermal Considerations
The MIC5205 is designed to provide 150 mA of
continuous current in a very small package. Maximum
power dissipation can be calculated based on the
output current and the voltage 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:
EQUATION 4-1:
T J MAX – T A
P D MAX = ----------------------------------- 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 4-1 shows
examples of junction-to-ambient thermal resistance for
the MIC5205.

(M5)
The actual power dissipation of the regulator circuit can
be determined using the equation:
EQUATION 4-2:
P D = V IN – V OUT I OUT + V IN I GND
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
MIC5205-3.3YM5 at room temperature with a minimum
footprint layout, the maximum input voltage for a set
output current can be determined as follows:

The junction-to-ambient thermal resistance for the
minimum footprint is 220°C/W, from Table 4-1. The
maximum power dissipation must not be exceeded for
proper operation. Using the output voltage of 3.3V and
an output current of 150 mA, the maximum input
voltage can be determined. From the Electrical
Characteristics table, the maximum ground current for
150 mA output current is 2500 µA or 2.5 mA.

Low Noise Fixed Voltage
Adjustable Regulator Applications
The MIC5205YM5 can be adjusted to a specific output
voltage by using two external resistors (Figure 4-3).
The resistors set the output voltage based on the
following equation:
EQUATION 4-7:
EQUATION 4-6:
V OUT = 1.242V R2
------- + 1
R1
950mW = V IN 152.5mA
VIN(MAX) then equates out to 6.23V. Therefore, a 3.3V
application at 150 mA of output current can accept a
maximum input voltage of 6.2V 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 Microchip’s Designing with Low-Dropout
Voltage Regulators handbook.
2017 Microchip Technology Inc.
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 and have a different VOUT equation.
Resistor values are not critical because ADJ (adjust)
has a high input impedance, but for best results use
resistors of 470 kΩ or less. A capacitor from ADJ to
ground provides greatly improved noise performance.

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.
