Key Features
- 300mA output current with only 200mV typical dropout voltage at full load
- Fixed 3.3V output in a tiny SOT-23-5 (5-pin) footprint ideal for space-constrained designs
- Shutdown pin (SHDN) for low-power control and wide input range of 3.7V to 6V
Applications
The MCP1824T-3302E/OT suits battery-powered portable devices such as handheld instruments and IoT sensor nodes that require a stable 3.3V rail from a single-cell lithium battery. Its ultra-low dropout of 200mV and 300mA current capacity also make it suitable for post-regulator applications in USB-powered and 5V industrial systems where tight headroom is critical.

Frequently Asked Questions
What is the maximum output current the MCP1824T-3302E/OT can supply continuously?
The MCP1824T-3302E/OT can deliver up to 300mA of continuous output current at a fixed 3.3V output, making it suitable for microcontrollers, sensors, and small RF modules operating from a 3.7V to 6V input supply.
How low can the input voltage be while the MCP1824T-3302E/OT maintains its 3.3V output regulation?
The regulator requires a minimum input of 3.7025V to maintain 3.3V regulated output, reflecting its typical 200mV dropout voltage at full 300mA load. At lighter loads the dropout is even lower, extending battery runtime in portable designs.
Which compact PCB designs benefit most from the SOT-23-5 package of this LDO?
The SOT-23-5 package measures only about 2.9mm x 1.6mm, saving significant board space in wearables, hearing aids, and IoT nodes. The 5-pin arrangement includes a shutdown pin for power-sequencing control, adding flexibility without increasing the footprint.
Can the MCP1824T-3302E/OT operate across industrial temperature ranges?
Yes. The device is specified over a -40°C to +125°C junction temperature range, qualifying it for industrial and automotive-adjacent applications where ambient temperatures exceed consumer grade requirements and reliability over wide thermal excursions is essential.
