The working principle of the MIC5305-1.8BD5 is fairly straightforward. The device uses a voltage reference and an error amplifier to compare the output voltage to a reference voltage. If the output voltage is too low, the error amplifier drives the control circuit, which increases the voltage being sent to the output. Conversely, if the output voltage is too high, the voltage sent to the output is decreased. The output voltage is then regulated until it matches the reference voltage. This process is repeated continuously in order to ensure that the output voltage remains stable over time.

Overall, the MIC5305-1.8BD5 is a versatile, feature-rich linear voltage regulator. Its low quiescent current allows it to operate efficiently in low power applications, while its wide operating temperature range and high accuracy make it suitable for a variety of applications.
