MIC5504-2.8YMT-T5

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The MIC5504-2.8YMT-T5 is a single-output low-dropout (LDO) voltage regulator manufactured by Microchip Technology, providing a fixed 2.8V output with a guaranteed maximum load current of 300 mA. It operates within an input voltage range of 2.5 V to 5.5 V and maintains high output accuracy of ±2%. The device features a low quiescent ground current of typically 38 μA and achieves a dropout voltage of 160 mV at full load. Designed for stability with 1 μF ceramic capacitors, it includes auto-discharge functionality and an internal enable pull-down resistor. The component is housed in a compact 4-lead 1.0 mm x 1.0 mm Thin DFN package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Includes an auto-discharge circuit that activates when the enable pin is low to discharge external capacitors.
• Features an internal pull-down resistor on the enable pin to disable the output when the control signal is floating.
• Provides linear current limiting and thermal shutdown protection against fault conditions.
