The MIC2951-3.3BM is a voltage regulator from the PMIC (Power Management Integrated Circuit) category, more specifically from the Voltage Regulators - Linear family. It is a below 2.4 volts, 1.5A (1.1A guaranteed) low drop-out voltage regulator with ultra-low quiescent current. This device provides many features and advantages that are perfect for mobile and battery-powered applications. Its stable voltage regulation, low power consumption, and low quiescent current make it an ideal voltage regulator for applications requiring full load operation and low power consumption.

The MIC2951-3.3BM is a combination of a high performance low drop-out regulator and a protection circuit that prevents short-circuit, over-temperature, over-current and reverse current conditions. The built-in protection circuitry ensures that the device can be safely operated in any environment. With an output accuracy of ±2%, the MIC2951-3.3BM can provide accurate and stable voltage regulation over a wide range of conditions. In addition, the device is capable of withstanding up to -4V of reverse voltage without damage.

The main operation of the MIC2951-3.3BM is to convert a low input voltage to a stable output voltage. This voltage regulator includes an internal N-Channel MOSFET pass element with a variable gate voltage controlled by an error amplifier. The internal PNP bipolar transistor adjusts the gate voltage of the MOSFET to balance the output load. The voltage feedback is sensed by the error amplifier and the output voltage is kept constant. The output voltage is internally set and is programmable with an external feedback resistor. This gives designers the flexibility to select the desired output voltage.

The MIC2951-3.3BM is the ideal device for mobile and battery-powered applications where low power consumption is a priority. Its low power consumption and low drop out voltage make it ideal for applications requiring full load operation and low current consumption. The built-in protection circuit ensures safe and efficient operation of the device. Finally, its flexibility in voltage programming provides designers the ability to set the desired output voltage.
