MIC2213
Sequenced Portable Power Management IC
General Description
Features
The MIC2213 is a dual µCap low dropout regulator with an
open-drain driver and power-on reset circuit. The first regu-
lator is capable of sourcing 150mA, while the second regula-
tor can source up to 300mA. A power-on reset function
monitors both outputs, indicating a fault on either output 1 or
output 2. The open-drain output is capable of sinking 150mA
for LED backlighting applications.
• 2 LDO outputs
• Output 1 - 150mA output current
• Output 2 - 300mA output current
• 1 Open-drain driver
• Power-on reset function with adjustable delay time
• Sequencing between outputs 1 and 2
• Input voltage range: 2.25V to 5.5V
• Stable with ceramic output capacitor
• Low dropout voltage of 80mV @ 100mA
• Ultra-low quiescent current of 48µA
• High output accuracy:
• +1.0% initial accuracy
• +2.0% over temperature
• Thermal Shutdown Protection
• Current Limit Protection
• Tiny 3mm × 3mm MLF™-10 package
The MIC2213 adds the additional feature of sequencing
between the outputs, with the output of regulator 1 having to
settle before the output of regulator 2 can begin to turn-on.
Ideal for battery operated applications, the MIC2213 offers
1% accuracy, extremely low dropout voltage (80mV @
100mA), and extremely low ground current, only 48µA total.
EquippedwithaTTLlogiccompatibleenablepin,theMIC2213
can be put into a zero-off-mode current state, drawing no
current when disabled.
Applications
• Cellular/PCS phones
• Wireless modems
• PDAs
The MIC2213 is a µCap design, operating with very small
ceramic output capacitors for stability, reducing required
board space and component cost.
The MIC2213 is available in fixed output voltages in the
10-pin 3mm × 3mm MLF™ leadless package and is also
available with adjustable output voltages in the 4mm × 4mm
16-pin MLF™ package.

Power-On Reset (POR)
Functional Description
The power-on reset output is an open-drain N-channel de-
vice, requiring a pull-up resistor to either the input voltage or
output voltage for proper voltage levels. The POR output has
a delay time that is programmable with a capacitor from the
SET pin to ground. The delay time can be programmed to be
as long as 1 second.
The MIC2213 is a high performance, low quiescent current
power management IC consisting of two µCap low dropout
regulators, a power-on reset (POR) circuit and an open-drain
driver. 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. The second regulator has a POR circuit that
monitors its output voltage and indicates when the output
voltage is within 5% of nominal. The POR offers a delay time
that is externally programmable with a single capacitor to
ground. An open-drain driver completes the power manage-
ment chipset, offering the capability of driving LEDs for
keypad backlighting in applications such as cellphones.
The SET pin is a current source output that charges a
capacitor that sets the delay time for the power-on reset
output. The current source is a 1µA current source that
charges a capacitor up from 0V. When the capacitor reaches
1.25V, the output of the POR is allowed to go high.
Open-Drain Driver (DRV)
The drive (DRV) pin is an open-drain output capable of
sinking 150mA of current. This output is controlled by a logic
level input, the switch (SW) pin. The switch pin is an active
high input and cannot be left floating.
Enable
The enable input allows for logic control of both output
voltages with one enable input. 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 MIC2213 can be by-
passed with a capacitor to ground to reduce output noise and
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.
Output Capacitor
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.
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-
tor with Y5V dielectric, the value must be much higher than a
X7R ceramic capacitor to ensure the same minimum capaci-
tance over the equivalent operating temperature range.
