The MIC2211-BF is a robust, low-power, single-channel, non-synchronous, low dropout (LDO) voltage regulator. The device provides programmable output voltage from 0.6V to 5V with a maximum output current of 1.5A. The extremely small range of THD (total harmonic distortion) and very low quiescent current of 1 µA make the MIC2211-BF the perfect choice for a variety of applications.

In addition to its wide adjustable range and low IQ, the MIC2211-BF features features such as a very low dropout voltage of 70 mV, buffer current mode control, programmable over current protection, and over temperature protection. The device has a wide operating range from -40ºC to +85ºC and is able to operate over an input voltage range of 2V to 6V. It also features low quiescent current, shift-and-load enable control, soft start control, and low output capacitance.

The MIC2211-BF is designed for linear voltage regulation applications in personal electronics, computing, telecommunications, and power management. It is suitable for applications such as PCMCIA cards, video game consoles, cameras, notebook computers, PDAs, satellite receivers, and cell phones.

The MIC2211-BF has an architecture consisting of two operational amplifier (op-amp) stages connected in series. The first stage is a folded cascode op-amp used as a buffer and the second is a gain stage. The gain is then shifted by a voltage-dividing resistor-capacitor network, which provides the voltage feedback loop control.

The MIC2211-BF has a very low dropout voltage of only 70 mV, making it ideal for battery powered applications. The device also features a built-in buffer current mode control for low output capacitance. The output voltage can be adjusted from 0.6V to 5V with a maximum output current of 1.5A.

The MIC2211-BF also features an over-current protection circuit that allows the output current to be set at a specific level. If the output current exceeds this level, an internal current mirror drives the output voltage to its own ground. The MIC2211-BF also features thermal shutdown protection above 135°C.

The MIC2211-BF has very low start-up and quiescent currents, making it ideal for battery-powered applications. The device also features programmable soft start and shift-and-load input enable control to reduce output in-rush current.

In summary, the MIC2211-BF is a low-power, single-channel, non-synchronous, low dropout (LDO) voltage regulator. It is suitable for linear voltage regulation applications, such as PCMCIA cards, video game consoles, cameras, notebook computers, PDAs, satellite receivers, and cell phones. The device features an adjustable voltage from 0.6V to 5V with a maximum current of 1.5A, low quiescent current, low dropout voltage of 70mv, programmable over-current protection, and thermal shutdown protection.
