What are the key features of MCP1702-3302E/TO?
- Fixed 3.3 V output, 250 mA LDO with wide input range of 4.15 V to 13.2 V for versatile power supply designs
- Low typical dropout of 0.525 V reduces minimum required input voltage for extended battery runtime
- Through-hole TO-92-3 package ideal for prototyping, hobbyist, and low-volume industrial applications
- Absolute maximum input rating of 14.5 V provides built-in margin against transient overvoltage conditions
What is MCP1702-3302E/TO used for?
The MCP1702-3302E/TO is suited for 3.3 V regulation in battery-powered devices, embedded systems, and small industrial controllers that use 9 V or 12 V unregulated supplies. Its 250 mA current capacity powers microcontrollers, sensors, and low-power wireless modules directly from the regulated rail. The TO-92-3 through-hole package makes it a practical choice for prototype boards, educational projects, and low-volume production where hand-soldering is preferred.

Frequently Asked Questions
What is the dropout voltage of the MCP1702-3302E/TO and how does it affect minimum input requirements?
The MCP1702-3302E/TO has a typical dropout voltage of 0.525 V and a maximum of 0.725 V at full 250 mA load. This means the minimum input voltage needed to maintain the 3.3 V output is approximately 4.025 V typical or 4.025 V to 4.149 V depending on load and temperature. This low dropout is beneficial when powering from a partially discharged 1S Li-ion cell or a 3-cell alkaline pack near end of life.
Can the MCP1702-3302E/TO regulate from a 9 V or 12 V supply without damage?
Yes, the MCP1702-3302E/TO accepts input voltages up to 13.2 V continuously with an absolute maximum of 14.5 V, making it directly compatible with 9 V and 12 V wall adapters and industrial power rails. The internal architecture handles the full voltage difference as a voltage drop across the pass element, but adequate heat sinking should be considered at 250 mA load with a 12 V input due to approximately 2.175 W of power dissipation.
How many milliamps can the MCP1702-3302E/TO supply, and what loads is that sufficient for?
The device delivers up to 250 mA of continuous output current at 3.3 V, which is sufficient to power a typical ARM Cortex-M microcontroller (20–80 mA), several I2C or SPI sensors (5–20 mA each), and a 2.4 GHz wireless module (up to 150 mA peak). For boards combining a microcontroller, a few peripherals, and short-range wireless, the 250 mA rating covers the combined average current comfortably.
What advantage does the TO-92-3 package offer compared to an SOT-23 LDO in prototyping scenarios?
The TO-92-3 through-hole package has 2.54 mm spaced leads that insert directly into standard breadboards and perfboards, eliminating the need for an SMD adapter board during development. At approximately 5 mm diameter, it is easy to handle and solder by hand, reducing assembly time in prototype builds. The TO-92 form factor is also widely stocked at electronics retail stores, improving local availability compared to fine-pitch SMD packages.
