Micrel Inc. • 2180 Fortune Drive • San Jose, CA 95131 • USA • tel +1 ( 408) 944-0800 • fax + 1 (408) 474-1000 • http://www.micrel.com November 2006 1 M9999-112006 General Description The MIC2210 is a dual µCap, 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 48µA 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 µCap 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 × 3mm MLF ® leadless package. Data sheets and support documentation can be found on Micrel’s web site at www.micrel.com. *For each output.
