The MIC5247-1.8YML-TR is a low-noise, low-dropout linear, positive voltage regulator from Micrel Inc. It is designed to provide a constant output voltage of 1.8V with a maximum input voltage rating of 5.5V, and an output current rating of 2A. The MIC5247-1.8YML-TR is ideally suited for applications that require a low-noise, low-dropout voltage regulator, such as battery-powered devices or portable electronics.

The MIC5247-1.8YML-TR features a built-in logic temperature shutdown with overtemperature protection and a manual reset input. It also features a disable control pin to reduce the current draw of the part during standby or shutdown modes. The MIC5247-1.8YML-TR is available in an 8-pin, DFN package and operates over the temperature range of -40°C to +125°C.

The MIC5247-1.8YML-TR is a one-time adjustable linear voltage regulator. It operates by taking a reference voltage from the output of the device, comparing it to an internal voltage reference and then making adjustments to the output reference voltage as needed. It does this by using a combination of current and voltage regulation to maintain a constant output voltage. The current regulation is done by varying the output impedance of the device and the voltage regulation is done by adjusting the reference voltage. The output voltage can be adjusted using an external resistor divider.

The MIC5247-1.8YML-TR has a wide input voltage range and can accept input voltages from 3V to 5.5V, making it suitable for battery-powered applications. It also has a low input quiescent current of 10uA and a low dropout voltage of 0.3V at full load, making it an ideal choice for low-noise, low-power applications. It features a wide line and load regulation of 5mV and 30mV, respectively, and a low output noise of 30uV RMS at 1kHz.

The MIC5247-1.8YML-TR is a cost-effective solution for low-noise, low-power voltage regulating applications. It can be used in a variety of applications including battery-powered devices, medical equipment, portable electronics, and automotive electronics. Its wide input voltage range, low dropout voltage, low noise, and high output current rating make it an ideal choice for low-power, low-noise applications.
