- Fixed 3.0 V output with 0.075% load regulation providing stable supply for microcontrollers and RF transceivers
- Wide 4.065 V to 13.2 V input voltage range covering 4xAA, 9 V, and 12 V battery or adapter inputs
- Compact SOT-23-3 package (PDSO-G3) minimizing PCB footprint in space-constrained wearable and portable designs
What is MCP1702-3002E/CB used for?
The MCP1702-3002E/CB is optimized for battery-powered wireless sensors, Bluetooth beacons, and IoT edge nodes where ultra-low quiescent current is critical to maximizing coin-cell or AA-battery service life measured in months or years. Its 625 mV dropout voltage allows continued 3.0 V regulation as a 3x AAA alkaline pack discharges toward 3.6 V, extracting near-full battery capacity without premature cutoff. The wide input range up to 13.2 V also accommodates 9 V alkaline and 12 V wall-adapter inputs, making it a versatile regulator for portable instrumentation and handheld testers.

Frequently Asked Questions
What dropout voltage and output current does the MCP1702-3002E/CB support for battery-powered designs?
The MCP1702-3002E/CB has a typical dropout voltage of 625 mV and a maximum of 975 mV at its full 250 mA output current, allowing it to maintain a stable 3.0 V regulated output when powered from a discharging 3x AAA alkaline pack dropping toward 3.6 V.
How does the ultra-low quiescent current of the MCP1702-3002E/CB extend battery runtime in IoT sensor nodes?
The MCP1702-3002E/CB's ultra-low quiescent current ensures that even in sleep modes where load drops below 1 µA, the regulator itself consumes minimal standby power, extending coin-cell or AA-battery service life from weeks to months in wireless sensor nodes that wake for 1 ms every 10 seconds.
What load and line regulation performance does the MCP1702-3002E/CB provide for powering RF transceivers?
The MCP1702-3002E/CB delivers 0.075% maximum load regulation and 0.082% maximum line regulation across its 4.065 V to 13.2 V input range, keeping the 3.0 V output within approximately 2.25 mV of nominal under transient load steps from a sleeping RF transceiver waking to transmit at 250 mA.
Which input voltage sources are compatible with the MCP1702-3002E/CB in portable and desktop instrument designs?
The MCP1702-3002E/CB accepts input voltages from 4.065 V to 13.2 V (absolute maximum 14.5 V), making it compatible with 4x AA alkaline (6 V), 9 V alkaline block batteries, 12 V wall adapters, and single-cell Li-ion packs in series, covering a broad range of portable instrument and handheld device power architectures.
