Key Features
- Fixed 1.2 V output with 2% accuracy across load and temperature
- 1.5 A continuous output current with only 0.33 V typical dropout voltage
- Wide input range of 2.3 V to 6 V supports single-cell Li-ion and 5 V rail applications
- TO-220-3 through-hole package simplifies heat-sinking for high-current designs
- Low quiescent current extends battery run time in portable and IoT equipment
Applications
MCP1827S-1202E/AB is used in battery-powered portable instruments, handheld test equipment, and embedded development boards where a stable 1.2 V logic rail must be derived from a 3.3 V or 5 V input. Its low 0.33 V dropout and 1.5 A current capability also make it suitable for point-of-load regulators in industrial control cards, FPGA core-voltage supplies, and any system requiring a robust TO-220 LDO with minimal external components.

Frequently Asked Questions
How low can the input voltage drop before MCP1827S-1202E/AB loses regulation at 1.5 A?
MCP1827S-1202E/AB has a typical dropout voltage of 0.33 V and a maximum of 0.6 V at full 1.5 A load. The device requires a minimum input of 2.3 V, so regulation is maintained down to roughly 1.53 V above the 1.2 V output under worst-case conditions.
In which applications is a fixed 1.2 V LDO like MCP1827S-1202E/AB preferred over an adjustable regulator?
Fixed-output LDOs are preferred when the system always uses 1.2 V for a DSP core, DDR memory termination, or FPGA I/O supply, since no external resistor divider is needed. MCP1827S-1202E/AB delivers 1.5 A at 1.2 V with 2% accuracy directly from its 3-pin TO-220 package, reducing BOM cost and eliminating resistor tolerance errors.
What is the absolute maximum input voltage for MCP1827S-1202E/AB, and does it survive 5 V USB supply transients?
The absolute maximum input voltage for MCP1827S-1202E/AB is 6.5 V, and the recommended operating maximum is 6 V. Standard 5 V USB rails and typical 5 V regulated supplies are well within this limit, so the device tolerates normal supply transients without damage when used in USB-powered or 5 V industrial power designs.
What RoHS and lead-free compliance status does MCP1827S-1202E/AB carry for export-controlled production?
MCP1827S-1202E/AB is lead-free and RoHS-compliant as indicated by the Pb-free code. It meets the JESD-609 e3 finish requirement, making it suitable for wave solder and reflow assembly on boards shipped into EU, China RoHS, and other restricted-substance regulated markets.
