General Description
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.
Features
• 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
