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
