MIC2211
Dual µCap LDO in 3mm × 3mm MLF™
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
• Tiny 10-pin 3mm × 3mm MLF™ package
Applications
• Cellular phones
• Wireless modems
• PDAs
