Working Principles

The MAX8887EZK15 is a voltage regulator that takes an input voltage within the range of 2.5V to 5.5V and provides a regulated output voltage between 1.2V and 3.6V. It operates by using a feedback mechanism to compare the output voltage with a reference voltage, adjusting the internal circuitry to maintain a stable output.

When the enable pin (EN) is high, the regulator is active and regulates the output voltage. Conversely, when the enable pin is low, the regulator enters a low-power shutdown mode, reducing power consumption.

Detailed Application Field Plans

The MAX8887EZK15 is commonly used in various portable electronic devices, such as smartphones, tablets, digital cameras, and portable media players. Its small package size and low quiescent current make it suitable for battery-powered applications where space and power efficiency are crucial.
