Frequently Asked Questions
Can MCP1702-3002E/TO regulate from a 9 V battery down to a stable 3.0 V rail for a microcontroller?
Yes. The MCP1702-3002E/TO accepts input voltages up to 13.2 V and delivers a fixed 3.0 V output at up to 250 mA, making it a straightforward choice for powering 3.3 V or 3.0 V microcontrollers directly from a 9 V alkaline battery.
How does the MCP1702 compare to other LDOs in designs where battery life is the top priority?
The MCP1702-3002E/TO has an ultralow quiescent current of approximately 2 µA, which is significantly lower than many standard LDOs, extending runtime in battery-powered IoT sensors, data loggers, and remote control devices where standby current dominates total power consumption.
What through-hole package options are available for the MCP1702-3002E/TO and how does it fit prototyping workflows?
The MCP1702-3002E/TO comes in a 3-pin TO-92 through-hole package, which inserts directly into standard breadboards and perfboards, simplifying prototyping and hand-assembly for low-volume production without requiring SMT reflow equipment.
Is MCP1702-3002E/TO suitable for designs with input voltages from unregulated wall adapters?
The device tolerates input voltages from 2.7 V to 13.2 V with an absolute maximum of 14.5 V, accommodating unregulated wall adapters that may vary between 9 V and 12 V nominal, provided the output current stays within the 250 mA rating.
