Introduction to MIC5247-1.8BD5-TR and Its Application Field

MIC5247-1.8BD5-TR is a low-input-bias-current, ultra-low-dropout, linear voltage regulator from the PMIC (Power Management Integrated Circuit) family of voltage regulators. It is designed for high-performance and low-power applications with a wide input voltage range of 1.45V to 9V. This reliable, cost-effective device provides low output impedance and fast transient response, allowing it to be used in a wide range of applications.

Application Field of MIC5247-1.8BD5-TR

The MIC5247-1.8BD5-TR is designed to be used in high-performance, low-power applications such as power supply design, power management, and power sequencing. It can also be used in embedded systems, digital video cameras, medical instruments, and portable devices. It is also an ideal voltage regulator for automotive and industrial applications, due to its low quiescent current and fast transient response.

Working Principle of MIC5247-1.8BD5-TR

The working principle of the MIC5247-1.8BD5-TR is fairly straightforward. It takes an input voltage, typically 5V, and regulates it to a precise output voltage. The device includes a band-gap reference and an error amplifier to maintain the output voltage accuracy. A precision resistor divider is used to set the output voltage. The output voltage is then fed back to the error amplifier to adjust the output if necessary. The output is then regulated using a low-side power MOSFET and an internal Auto-Tracking low-side driver circuit. The Auto-Tracking low-side driver circuit is designed to optimize efficiency, by ensuring that the output voltage adjusts correctly based on the input voltage.

The MIC5247-1.8BD5-TR also includes a number of protection features, including over-temperature and short-circuit protection. The over-temperature protection shuts down the output when the temperature exceeds a predetermined limit. The short-circuit protection senses when the output voltage reaches a certain level and shuts off the output.
