MIC2215
High PSRR, Low Noise μCap Triple LDO
Features
General Description
• Input Voltage Range: +2.25V to +5.5V
• 70 dB PSRR
The MIC2215 is a high performance, triple LDO voltage
regulator, with each regulator capable of providing
250 mA continuous output current.
• Stable with Ceramic Output Capacitor
• High Output Accuracy:
Ideal for battery-operated applications, the MIC2215
offers 1% initial accuracy, extremely low dropout
voltage (100 mV @ 150 mA), and low ground current at
light load (typically 110 μA per regulator). Equipped
with a noise bypass pin and featuring very high power
supply ripple rejection (PSRR) of up to 80 dB, the
MIC2215 provides the lowest noise and highest
efficiency solution for RF applications in portable
electronics such as cellular phones and wireless LAN
applications.
- ±1.0% Initial Accuracy
- ±2.0% over Temperature
• Low Dropout Voltage of 100 mV @ 150 mA
• Low Quiescent Current: 110 μA per Regulator
• Fast Turn-On Time: 30 μs
• Zero Off-Mode Current
• Thermal Shutdown Protection
• Current Limit Protection
Equipped with TTL logic-compatible enable pins, each
of the regulators in the MIC2215 can be put into a zero
current off mode where the supply current is much less
than 1 μA when all the regulators are disabled. The
MIC2215 is a μCap design, which enables a stable
output with small ceramic output capacitors, reducing
both cost and required board space for output
bypassing.
• Tiny 16-Pin 4 mm x 4 mm QFN Package
Applications
• Cellular Phones
• PCs and Peripherals
• Wireless LAN Cards
• PDAs
The MIC2215 is available in the miniature 16-pin,
4 mm x 4 mm QFN package.
• GPS

† 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 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.
2: Devices are ESD sensitive. Handling precautions recommended.

Note 1: 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.

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.

Designed specifically for noise-critical applications in
handheld or battery-powered devices, the MIC2215
comes equipped with a noise reduction feature to filter
the output noise via an external capacitor. Other
features of the MIC2215 include a separate logic
compatible enable pin for each channel, current limit,
thermal shutdown, and ultra-fast transient response, all
within a small QFN package.
5.4
Bypass Pin
A capacitor can be placed from the noise bypass pin to
ground to reduce output voltage noise. The capacitor
bypasses the internal reference. There is one single
internal reference shared by each output, therefore the
bypassing affects each regulator. A 0.1 μF capacitor is
recommended for applications that require low-noise
outputs. The bypass capacitor can be increased,
further reducing noise and improving PSRR. Turn-on
time increases slightly with respect to bypass
capacitance.
The MIC2215 is specifically designed to work with
low-ESR ceramic capacitors, reducing the amount of
board space necessary for power applications, which is
critical in handheld wireless devices.

5.1
APPLICATION INFORMATION
Enable/Shutdown
The MIC2215 comes with three active-high enable pins
that allow each individual regulator to be either
disabled or enabled. Forcing the enable pin low
disables the respective regulator and sends it into a
zero off-mode current state. In this state, current
consumed by the individual regulator goes nearly to
zero. This is true for both regulators 2 and 3. Regulator
1’s input supply pin is also used to power the internal
reference. When any regulator, either 1, 2, or 3, is
enabled, an additional 20 μA for the reference will be
drawn through VIN1. All three must be disabled to enter
the zero current off-mode state. Forcing the enable pin
high enables each respective output voltage. This part
is CMOS and none of the enable pins can be left
5.5
Internal Reference
The internal band gap, or reference, is powered from
the VIN1 input. Due to some of the input noise (PSRR)
contributions being imposed on the band gap, it is
important to make VIN1 as clean as possible with good
bypassing close to the input.
5.6
Multiple Input Supplies
The MIC2215 can be used with multiple input supplies
when desired. The only requirement, aside from
maintaining the voltages within the operating ranges, is
that VIN1 always remains the highest voltage potential.
floating;
a floating enable pin may cause an
indeterminate state on the output.
5.7
No-Load Stability
5.2
Input Capacitor
The MIC2215 will remain stable and in regulation with
no load, unlike many other voltage regulators. This is
especially important in CMOS RAM keep-alive
applications.
The MIC2215 is a high performance, high bandwidth
device. Therefore, it requires a well-bypassed input
supply for optimal performance. A small 0.1 μF
capacitor placed close to the input is recommended to
aid in noise performance. Low-ESR ceramic capacitors
provide optimal performance at a minimum of space.
Additional high-frequency capacitors, such as small
valued NPO dielectric type capacitors, help to filter out
high frequency noise and are good practice in any
RF-based circuit.
5.8
Thermal Considerations
The MIC2215 is designed to provide up to 250 mA of
current per channel 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:
5.3
Output Capacitor
The MIC2215 requires an output capacitor for stability.
The design requires 1 μF or greater on the output to
maintain stability. The design is optimized for use with
low-ESR ceramic chip capacitors. X7R/X5R
dielectric-type ceramic capacitors are recommended
because of their temperature performance. X7R-type
capacitors change capacitance by 15% over their

temperature for a 125°C junction temperature.
Calculating maximum ambient temperature follows:
EQUATION 5-5:
The actual power dissipation of the regulator circuit can
be determined using the following equation:
T AMAX = T J MAX – PD JA
T AMAX = 125C – 540mW 43C/W
T AMAX = 101C
EQUATION 5-2:
PDTOTAL = PDLDO1 + PDLDO2 + PDLDO3
Where:
P
DLDO1 = (VIN1 – VOUT1) x IOUT1
For more information, please refer to the Designing
with Low-Dropout Voltage Regulators Handbook.
PDLDO2 = (VIN2 – VOUT2) x IOUT2
PDLDO3 = (VIN3 – VOUT3) x IOUT3
5.9
Adjustable Regulator Application
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
MIC2215 at 60°C with a minimum footprint layout, the
maximum load currents can be calculated as follows:
Adjustable regulators use the ratio of two resistors to
multiply the reference voltage to produce the desired
output voltage. The MIC2215 can be adjusted from
1.25V to 5.5V, the maximum VDROPOUT, by using two
external resistors (Figure 5-1). The resistors set the
output voltage based on the following equation:
EQUATION 5-3:
EQUATION 5-6:
PDMAX = 125C – 60C 43C/W = 1.511W
R1
R2
V OUT = V REF 1 + ------
The junction-to-ambient thermal resistance for the
minimum footprint is 43°C/W. The maximum power
dissipation must not be exceeded for proper operation.
Using a lithium-ion battery as the supply voltage
(2.8V/250 mA for channel 1, 3V/100 mA for channel 2,
and 2.8V/50 mA for channel 3), maximum power can
be calculated as follows:
Where:
V
REF = 1.25V

EQUATION 5-4:

R2
PDLDO1 = 4.2V – 2.8V 250mA
PDLDO1 = 350mW
PDLDO2 = 4.2V – 3.0V 100mA
PDLDO2 = 120mW
PDLDO3 = 4.2V – 2.8V 50mA
PDLDO3 = 70mW
FIGURE 5-1:
Adjustable Output.
PDTOTAL = 350mW + 120mW + 70mW
PDTOTAL = 540mW
The calculation shows that the device is well below the
maximum allowable power dissipation of 1.511W for a
60°C ambient temperature. After the maximum power
dissipation has been calculated, it is always good
