MIC2211
Dual µCap LDO in 3mm × 3mm MLF™
General Description
Features
The MIC2211 is a dual µCap, low dropout regulator. The first
regulator is capable of sourcing 150mA, while the second
regulator can source up to 300mA.
Ideal for battery operated applications, the MIC2211 offers
1% accuracy, extremely low dropout voltage (80mV @
100mA), and extremely low ground current, only 48µA total.
Equipped with TTL logic compatible enable pins, the MIC2211
can be put into a zero-off-mode current state, drawing no
current when disabled. Separate enable pins allow individual
control of each output voltage.
The MIC2211 is a µCap design, operating with very small
ceramic output capacitors for stability, reducing required
board space and component cost.
The MIC2211 is available in fixed output voltages in the
10-pin 3mm × 3mm MLF™ leadless package.
• Input voltage range: 2.25V to 5.5V
• Stable with ceramic output capacitor
• 2 LDO outputs
• Output 1 - 150mA output current
• Output 2 - 300mA output current
• Low dropout voltage of 80mV @ 100mA
µA total (24µ
µA/LDO)
• Ultra-low quiescent current of 48µ
• High output accuracy:
• +1.0% initial accuracy
• +2.0% over temperature
• Thermal shutdown protection
• Current limit protection
• Tiny 10-pin 3mm × 3mm MLF™ package
Applications
• Cellular phones
• Wireless modems
• PDAs

Notes:
1. Exceeding maximum rating may damage the device.
2. The device is not guaranteed to work outside its operating rating.
3. 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.
4. Specification for packaged product only.
5. Minimum input for line regulation test is set to VOUT + 1V relative to the highest output voltage.
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. For outputs below 2.25V, dropout voltage is the input-to-output voltage differential with the minimum input voltage 2.25V. Minimum input
operating voltage is 2.25V.

Functional Description
increase power supply rejection (PSRR). A quick-start feature allows for quick turn-on of the output voltage regardless
of the size of the capacitor. The recommended nominal
bypass capacitor is 0.01µF, but it can be increased without
limit.
Output Capacitor
Each regulator output requires a 1µF ceramic output capacitor for stability. The output capacitor value can be increased
to improve transient response, but performance has been
optimized for a 1µF ceramic type output capacitor.
X7R/X5R dielectric-type ceramic capacitors are recommended because of their temperature performance. X7Rtype capacitors change capacitance by 15% over their 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.
The MIC2211 is a high performance, low quiescent current
power management IC consisting of two µCap low dropout
regulators. The first regulator is capable of sourcing 150mA
at output voltages from 1.25V to 5V. The second regulator is
capable of sourcing 300mA of current at output voltages from
1.25V to 5V.
Enable 1 and 2
The enable inputs allow for logic control of both output
voltages with individual enable inputs. The enable input is
active high, requiring 1.8V for guaranteed operation. The
enable input is CMOS logic and cannot by left floating.
Input Capacitor
Good bypassing is recommended from input to ground to
help improve AC performance. A 1µF capacitor or greater
located close to the IC is recommended.
Bypass Capacitor
The internal reference voltage of the MIC2211 can be bypassed with a capacitor to ground to reduce output noise and
