Overview
The MIC5504-3.3YM5-TR is a fixed output, single low dropout (LDO) voltage regulator produced by Microchip Technology. This device is packaged in a 5-pin SOT-23 package and is designed for high-performance applications, particularly in battery-powered devices. It features an auto-discharge function on the output when the enable pin is low, and an internal pull-down resistor on the enable pin to ensure the output is disabled when the enable pin is left floating. This makes it ideal for applications where the control signal may be floating during processor boot-up. The regulator can also be put into a zero-off mode, drawing virtually no current when disabled.
