Applications
MCP1824ST-5002E/DB generates a clean 5 V regulated supply from a 5 V USB input or wall adapter with minimal dropout, making it ideal for USB-powered consumer electronics and embedded systems requiring noise-free analog supply rails. Its 200 mV nominal dropout allows it to maintain regulation even as a 5 V input bus sags under load, supporting microcontrollers, sensors, and interface ICs with stable voltage in SOT-223-3 packages. Industrial control panels and test equipment use it as a post-regulator to filter noise from switching supplies feeding sensitive analog signal chains.

Frequently Asked Questions
What is the dropout voltage of MCP1824ST-5002E/DB, and how close to 5 V can the input voltage be?
MCP1824ST-5002E/DB has a nominal dropout voltage of 200 mV and a maximum dropout of 320 mV. This means the input voltage needs to be at least 5.2 V nominally—or 5.32 V under worst-case conditions—to maintain a regulated 5 V output. The specified input voltage range starts at 5.445 V, providing additional margin against load and temperature variation while the absolute maximum input is 6.5 V.
How does MCP1824ST-5002E/DB perform as a post-regulator after a 5 V switching supply?
Switching supplies typically produce a 5 V rail with 50 mV to 100 mV of ripple. Placing MCP1824ST-5002E/DB after the switcher attenuates this ripple by the LDO's power-supply rejection ratio, producing a much cleaner 5 V for analog circuits and sensitive RF front ends. The 200 mV nominal dropout means the switching supply's output must be set to at least 5.2 V to keep the LDO in regulation, which is practical for most adjustable switchers.
Why is the SOT-223-3 package advantageous for MCP1824ST-5002E/DB in thermally demanding applications?
The SOT-223-3 package includes a large exposed metal tab fused to the output pin, which directly contacts PCB copper for conductive heat spreading. Compared to SOT-23 or TSOT packages, this tab dramatically reduces junction-to-board thermal resistance, allowing the MCP1824ST-5002E/DB to dissipate more power before reaching its 125°C maximum junction temperature. For a 5 V output drawing 300 mA from a 6 V input, the 300 mW dissipation is safely managed with even minimal copper pour.
Which embedded system power rails benefit from MCP1824ST-5002E/DB as an analog supply reference?
Analog front-end circuits, precision ADC reference pins, and audio codec supply rails all benefit from the clean 5 V output of MCP1824ST-5002E/DB because LDO regulators produce substantially lower output noise than switching converters. Microcontroller AVDD pins and operational amplifier supply rails in data acquisition systems particularly require a stable 5 V with less than 50 µV RMS noise, which this SOT-223-3 LDO can provide from a 5.445 V to 6 V input with proper output capacitor selection.
