What are the key features of MCP1702T-1502E/CB?
- Fixed 1.5V output LDO regulator capable of sourcing up to 250 mA with only 1.2V typical dropout voltage, enabling operation from nearly depleted Li-ion or 3xAA battery packs
- Wide input voltage range from 2.7V to 13.2V accommodating diverse supply sources including 9V alkaline batteries, 12V adapters, and USB power banks without additional pre-regulation
- Compact 3-pin SOT-23A package with no external adjust components required, minimizing PCB footprint and simplifying power supply design for space-constrained wearable and IoT applications
What is MCP1702T-1502E/CB used for?
The MCP1702T-1502E/CB is an excellent choice for powering low-voltage microcontrollers, Bluetooth Low Energy modules, and MEMS sensors in battery-operated IoT nodes and wearable devices that require a stable 1.5V rail from variable or unregulated supply sources. Its wide 2.7V to 13.2V input range and 250 mA current capability also make it suitable as a post-regulator in USB-powered devices and 9V to 12V wall-adapter powered sensor hubs.

Frequently Asked Questions
What is the output voltage and maximum output current of the MCP1702T-1502E/CB, and can it power a Bluetooth LE module directly?
The MCP1702T-1502E/CB provides a fixed 1.5V output at up to 250 mA, which is sufficient for most Bluetooth Low Energy SoCs that draw under 15 mA in transmit mode and under 5 mA in sleep mode, though a BLE module with an external PA exceeding 250 mA would need a higher-current regulator.
What is the dropout voltage of the MCP1702T-1502E/CB, and at what battery voltage does it stop regulating from a 2xAA cell stack?
The typical dropout voltage is 1.2V, meaning the 1.5V output regulates correctly as long as the input remains above 2.7V; a 2×AA alkaline stack starting at 3.0V fully charged will lose regulation when the batteries discharge below approximately 2.7V, which corresponds to near end-of-life for alkaline cells.
How does the 2.7V to 13.2V input range of the MCP1702T-1502E/CB benefit a multi-source IoT power design?
The 2.7V to 13.2V input range allows the same MCP1702T-1502E/CB to be powered from a 3V coin cell, a 9V alkaline battery, or a 12V DC adapter depending on application context, eliminating the need to select different regulators for each supply scenario and reducing SKU complexity.
Does the MCP1702T-1502E/CB require external compensation capacitors, and what is the minimum output capacitor needed for stability?
The MCP1702T-1502E/CB is stable with a minimum 1 µF ceramic output capacitor and requires no external compensation network; its internal fixed frequency architecture and PMOS pass element eliminate the ESR sensitivity issues common to older NPN-based LDOs, simplifying the PCB layout.
