Frequently Asked Questions
What input voltage range does the MCP1702-5002E/TO accept, and can it regulate from a standard 9 V alkaline battery?
The MCP1702-5002E/TO accepts input voltages from 5.8 V to 13.2 V, making it fully compatible with a fresh 9 V alkaline battery that starts at approximately 9.6 V and discharges down to 6 V. The 330 mV typical dropout means the 5 V output stays regulated until the battery drops to about 5.33 V, extending useful battery life compared to higher-dropout alternatives.
How does the MCP1702-5002E/TO's 250 mA current rating compare to requirements for typical 5 V microcontroller systems?
Most 5 V microcontrollers such as AVR and PIC devices draw 10 mA to 50 mA in active mode, and common peripherals like LCD modules, sensors, and LEDs may add another 50 mA to 100 mA, totaling well within the 250 mA capacity of the MCP1702-5002E/TO. This makes it a right-sized, cost-effective regulator for standalone microcontroller boards without the overhead of a higher-current device.
For a prototype using a breadboard, why might a designer choose the TO-92-3 MCP1702-5002E/TO over an equivalent SOT-23 LDO?
The TO-92-3 package has 1.27 mm spaced leads that plug directly into standard 0.1-inch (2.54 mm) breadboard holes, whereas SOT-23 SMD packages require an adapter PCB or breakout board for prototyping. For rapid prototyping, educational labs, and low-volume hand-assembled boards, the TO-92-3 form factor saves time and eliminates the soldering skill required to place 1.9 mm x 3 mm SMD packages.
