Portable Power Management IC
General Description
The MIC2214 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 MIC2214 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 MIC2214 can be put into a zero-off-mode current state, drawing no current when disabled. The MIC2214 is a µCap design, operating with very small ceramic output capacitors for stability, reducing required board space and component cost. The MIC2214 is available in fixed output voltages in the 10-pin 3mm × 3mm MLFTM leadless package and is also available with adjustable output voltages in the 4mm × 4mm 16-pin MLFTM package.

Active High. High = on, low = off. Do not leave floating. Enable Input to Regulator 1: Enables regulator 1 output. Active high input. High = on, low = off. Do not leave floating. Enable Input to Regulator 2: Enables regulator 2 output. Active high input. High = on, low = off. Do not leave floating. Reference Bypass: Connect external 0.01µF to GND to reduce output noise. May be left open. Active high signal drives open-drain N-Channel MOSFET. Adjust Input (Regulator 1): Connect feedback resistors to program the output voltage for the regulator. Delay Set Input: Connect external capacitor to GND to set the internal delay for the POR output. When left open, there is no delay. This pin cannot be grounded. Ground: Connect externally to exposed pad. Ground for the open-drain driver. Tied to the source of the NMOSFET. Tied to GND internally. Adjust Input (Regulator 2): Connect feedback resistors to program the output voltage for the regulator. Open-Drain Output: Capable of sinking 150mA. Power-On Reset Output: Open-drain output. Active low indicates an output undervoltage condition on regulator 2. Output of Regulator 2: 300mA output current Output of Regulator 1: 150mA output current Ground: Internally connected to the exposed pad. Connect externally to ground pin.
