Applications
MCP1702T-2802E/CB regulates power for wireless sensor nodes, RF front-end modules, and low-power microcontrollers that require a stable 2.8 V supply derived from a wide-range input such as a 9 V alkaline battery or 12 V bus. Its low quiescent current and SOT-23 footprint make it ideal for coin-cell-derived supplies in IoT devices and wearable medical sensors. Designers also use it to supply 2.8 V camera modules and LCD bias rails in portable consumer electronics.

Frequently Asked Questions
What is the dropout voltage of MCP1702T-2802E/CB at full load, and how does it affect battery life?
MCP1702T-2802E/CB has a typical dropout voltage of 625 mV and a maximum of 975 mV at 250 mA output current. This means the regulator maintains 2.8 V output as long as the input stays above approximately 3.425 V typical, allowing a Li-ion cell to discharge further before the output drops out and extending effective battery run time in portable designs.
Can MCP1702T-2802E/CB be used directly with a 12 V automotive supply?
Yes, MCP1702T-2802E/CB accepts input voltages up to 13.2 V continuously and survives transients to 14.5 V absolute maximum, making it compatible with a 12 V automotive nominal bus. The regulator steps down the 12 V input to a stable 2.8 V output at up to 250 mA, but designers should verify the power dissipation of (12 V - 2.8 V) × 250 mA = 2.3 W does not exceed the SOT-23 thermal limits without adequate PCB copper area.
How small is the external component footprint required by MCP1702T-2802E/CB?
MCP1702T-2802E/CB requires only a 1 µF output capacitor for stability and a 1 µF input bypass capacitor, giving a total external component count of just 2 passive devices. The SOT-23 3-pin package itself measures 2.9 mm × 1.6 mm, so the entire regulator solution fits in under 25 mm² of PCB area, making it one of the most compact 250 mA LDO solutions available.
How does MCP1702T-2802E/CB compare to a 2.8 V LDO from the MCP1703 family for high-input-voltage designs?
MCP1702T-2802E/CB is rated to 13.2 V input compared to the MCP1703 family's 16 V maximum, but both share the SOT-23 package and 250 mA capability. For input voltages between 3.4 V and 13.2 V the MCP1702T-2802E/CB is the lower-cost option with a 0.4 % output accuracy, while designs exceeding 13.2 V input require the higher-voltage MCP1703 variant.
