MIC2210
Dual Cap LDO with Open-Drain Driver REV. 11/04
General Description
The MIC2210 is a dual Cap low dropout regulator with an open-drain driver and power-on reset circuit. The first regulator is capable of sourcing 150mA, while the second regulator can source up to 300mA and includes a power-on reset function. The open-drain output is capable of sinking 150mA for LED backlighting applications. Ideal for battery operated applications, the MIC2210 offers 1% accuracy, extremely low dropout voltage (80mV @ 100mA), and extremely low ground current, only 48A total. Equipped with a TTL logic compatible enable pin*, the MIC2210 can be put into a zero-off-mode current state, drawing no current when disabled. The MIC2210 is a Cap design, operating with very small ceramic output capacitors for stability, reducing required board space and component cost. The MIC2210 is available in fixed output voltages in the 10-pin 3mm x 3mm MLFTM leadless package and is also available with adjustable output voltages in the 4mm x 4mm 16-pin MLFTM package.

Exceeding maximum rating may damage the device. The device is not guaranteed to work outside its operating rating. The maximum allowable power dissipation of any TA (ambient temperature) is (PD(max) = TJ(max) - TA) / JA. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. Specification for packaged product only. Minimum input for line regulation test is set to VOUT + 1V relative to the highest output voltage. 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.

Functional Description
The MIC2210 is a high performance, low quiescent current power management IC consisting of two Cap low dropout regulators, 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. An open-drain driver completes the power management chipset, offering the capability of driving LEDs for keypad backlighting in applications such as cellphones. 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. 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. Input Capacitor Good bypassing is recommended from input to ground to help improve AC performance. A 1F capacitor or greater located close to the IC is recommended.

MIC2210
MIC2210 Bypass Capacitor The internal reference voltage of the MIC2210 can be bypassed with a capacitor to ground to reduce output noise and increase power supply rejection (PSRR). 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 0.01F, but it can be increased without limit.
Micrel Output Capacitor Each regulator output requires a 1F ceramic output capacitor for stability. The output capacitor value can be increased to improve transient response, but performance has been optimized for a 1F ceramic type output capacitor. X7R/X5R dielectric-type ceramic capacitors are recommended because of their temperature performance. X7R-type 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 a X7R ceramic capacitor to ensure the same minimum capacitance over the equivalent operating temperature range.
