MIC5247-2.2BM5-TR is a linear voltage regulator designed by MICREL Inc. It is part of their wide range of power management integrated circuits (PMICs). The device is designed to provide high performance, low-noise and low power linear regulation of power output and input voltage. It is suitable for a variety of applications such as powering logic, processors and systems, providing embedded power for mobile and consumer electronics, and providing regulated power for communications and industrial applications.

The MIC5247-2.2BM5-TR has an output voltage range from 1.2V to 5.5V, with a maximum output current of 250 mA. It can handle input voltages up to 15V, and has a dropout voltage of only 600 mV. In addition, it is designed internally with a high ripple rejection, allowing it to effectively eliminate power supply noise. The device also has a high switching frequency, allowing it to achieve high efficiency and fast transient response. It is available in three packages; SOT-23-5, MSOP-10 and TSSOP-10.

The linear voltage regulator is designed to work with a fixed output voltage. It uses a resistor divider to compare the output voltage to a reference voltage, and then adjusts the control voltage at the base to regulate the output voltage. The control voltage is determined from the difference between the reference voltage and the output voltage. This regulation technique ensures that the output voltage remains stable under changing input voltage levels and varying load requirements.

The MIC5247-2.2BM5-TR offers a thermal protection circuit, which protects the device from damaging over-temperature conditions. It also offers a current limiting circuit which results in a slow rise in output voltage when the load current falls below regulation levels. This prevents over-voltage spikes which might otherwise damage sensitive circuitry.

In addition, the voltage regulator provides detailed device functionality without the need of external components. The device automatically provides protection against open-loop, short-circuit, over-current and over-temperature conditions. It also incorporates a power-on reset circuit, which ensures proper device operation when the power is first applied.

Overall, the MIC5247-2.2BM5-TR is a great choice for many linear voltage regulator applications. It provides high performance, low noise and low power regulation, and is designed to make implementation and operation easy. With its wide input voltage range, fast transient response and excellent regulation features, the device is ideal for a variety of power management needs.
