The MAX1722EZK+T has a total of 5 pins:
The MAX1722EZK+T is a voltage regulator IC that takes an input voltage within the range of 2.7V to 5.5V and provides a regulated output voltage between 1.8V and 3.3V. It achieves this by using a step-down (buck) converter topology.
The regulator operates by continuously monitoring the output voltage through the feedback pin (FB). If the output voltage falls below the desired level, the regulator adjusts its internal circuitry to increase the output voltage. Conversely, if the output voltage exceeds the desired level, the regulator reduces the output voltage.
The enable pin (EN) allows the user to turn the regulator on or off as needed. When the enable pin is low, the regulator enters a low-power shutdown mode, reducing power consumption to a minimum.
The MAX1722EZK+T is commonly used in various battery-powered applications, such as:
Due to its low quiescent current and high efficiency, the MAX1722EZK+T is particularly suitable for applications where power efficiency and extended battery life are crucial.
These alternative models provide flexibility in choosing the right voltage regulator based on specific application requirements.
