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.
• 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
• Ultra-low quiescent current of 48µA total (24µA/LDO)
• High output accuracy:
• +1.0% initial accuracy
• +2.0% over temperature
• Thermal shutdown protection
• Current limit protection
• Tiny 10-pin 3mm × 3mm MLF™ package
Ideal for battery operated applications, the MIC2211 offers
1% accuracy, extremely low dropout voltage (80mV @
100mA), and extremely low ground current, only 48µA total.
EquippedwithTTLlogiccompatibleenablepins,theMIC2211
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.
Applications
The MIC2211 is available in fixed output voltages in the
10-pin 3mm × 3mm MLF™ leadless package.
• Cellular phones
• Wireless modems

Functional Description
increase power supply rejection (PSRR). A quick-start fea-
ture 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.
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.
Output Capacitor
Enable 1 and 2
Each regulator output requires a 1µF ceramic output capaci-
tor 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.
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.
X7R/X5R dielectric-type ceramic capacitors are recom-
mended because of their temperature performance. X7R-
type capacitors change capacitance by 15% over their oper-
ating temperature range and are the most stable type of
ceramiccapacitors.Z5UandY5Vdielectriccapacitorschange
value by as much as 50% and 60% respectively over their
operatingtemperatureranges. Touseaceramicchipcapaci-
torwithY5Vdielectric, thevaluemustbemuchhigherthanan
X7R ceramic capacitor to ensure the same minimum capaci-
tance over the equivalent operating temperature range.
Input Capacitor
Good bypassing is recommended from input to ground to
