MIC2211 Micrel 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. 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. • 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 µA total (24µ µA/LDO) • Ultra-low quiescent current of 48µ • 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 Typical Application MIC2211-xxBML OFF ON OFF ON VIN VOUT1 EN1 VOUT2 VI/O VCORE 1µF Ceramic EN2 1µF Baseband µProcessor CBYP 0.01µF GND MIC2211 Typical Cell Phone Application MicroLeadFrame and MLF are trademarks of Amkor Technology, Inc.

Exceeding maximum rating may damage the device. 2. The device is not guaranteed to work outside its operating rating. 3. The maximum allowable power dissipation of any TA (ambient temperature) is (PD(max) = TJ(max) – TA) / θJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. 4. Specification for packaged product only. 5. Minimum input for line regulation test is set to VOUT + 1V relative to the highest output voltage. 6. Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below its nominal value measured at 1V differential. For outputs below 2.25V, dropout voltage is the input-to-output voltage differential with the minimum input voltage 2.25V. Minimum input operating voltage is 2.25V.

A quick-start feature 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 capacitor 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 recommended because of their temperature performance. X7Rtype capacitors change capacitance by 15% over their operating temperature range and are the most stable type of ceramic capacitors. Z5U and Y5V dielectric capacitors change value by as much as 50% and 60% respectively over their operating temperature ranges. To use a ceramic chip capacitor with Y5V dielectric, the value must be much higher than an X7R ceramic capacitor to ensure the same minimum capacitance over the equivalent operating temperature range. 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. Enable 1 and 2 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. 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 MIC2211 can be bypassed with a capacitor to ground to reduce output noise and M9999-090204 8 August 2004 MIC2211 Micrel Package Information 0.85 +0.15 —0.05 1.60 +0.15 —0.15 3.00 BSC. 0.80 +0.15 —0.15 1.50 BSC. 0.01 +0.04 —0.01 0.48 typ.
