Key Features
- Fixed 1.2 V output at up to 250 mA with a wide input range from 2.7 V to 13.2 V, accommodating diverse system rails
- SOT-23A-3 (3-pin) package providing an extremely compact footprint for space-constrained RF modules and processor core rails
- 1.5 V typical dropout voltage enabling regulation from common 3.3 V or higher rails down to a low 1.2 V processor core supply
Applications
The MCP1702T-1202E/CB is designed to supply 1.2 V processor core rails, memory interfaces, and low-voltage logic from higher-voltage bus rails in portable electronics, IoT modules, and embedded computing boards. Its wide 2.7 V to 13.2 V input range makes it compatible with single-cell Li-ion, regulated 5 V, and 12 V system supplies in the same PCB design. The compact SOT-23 package minimizes board area next to microcontrollers and FPGAs requiring a stable low-voltage core supply.

Frequently Asked Questions
What input voltage range does MCP1702T-1202E/CB support, and how does this help in multi-rail system designs?
MCP1702T-1202E/CB accepts input voltages from 2.7 V up to 13.2 V, making it compatible with 3.3 V, 5 V, and 12 V supply rails. This single-device flexibility simplifies BOM management when multiple supply scenarios exist on the same embedded platform requiring a 1.2 V core rail.
For a wireless sensor node, how does MCP1702T-1202E/CB's SOT-23 package benefit PCB space management near an RF module?
The SOT-23A-3 package occupies less than 3 mm x 3 mm of PCB area, allowing the 1.2 V regulator to sit directly adjacent to an RF SoC or microcontroller core power pin. At 250 mA maximum output current and 1.5 V dropout, it delivers a clean 1.2 V rail without requiring additional filtering inductors.
How does the 1.5 V dropout voltage of MCP1702T-1202E/CB affect its use with a 3.3 V input supplying a 1.2 V core?
With a 1.5 V typical dropout, MCP1702T-1202E/CB requires the input to be at least 2.7 V to maintain 1.2 V output, which is easily met by a 3.3 V rail leaving 2.1 V headroom at full 250 mA load. This headroom is sufficient to keep the output in regulation across PCB trace voltage drops and supply transients in most embedded designs.
