Key Features

  • Fixed 1.8 V output LDO regulator with 1.5 A maximum output current
  • Ultra-low nominal dropout voltage of 0.33 V for high efficiency
  • Wide input voltage range of 2.44 V to 6 V for flexible power supply topologies
  • Absolute maximum input voltage of 6.5 V for transient protection
  • TO-220-3 through-hole package with excellent thermal dissipation capability
  • RoHS-compliant lead-free construction

Applications

The MCP1827S-1802E/AB is well suited for powering FPGA core voltage rails, DSP and processor I/O banks, and high-current 1.8 V digital logic supplies where up to 1.5 A of continuous current is required with low dropout. Its TO-220-3 through-hole package is commonly used in benchtop power supplies, lab evaluation boards, and industrial prototyping platforms where heatsink attachment and easy component replacement simplify thermal management.

Frequently Asked Questions

How much output current can MCP1827S-1802E/AB supply, and is 1.5 A sufficient for powering FPGA core rails?

The MCP1827S-1802E/AB can supply up to 1.5 A of continuous output current at 1.8 V, which is sufficient for many low- to mid-range FPGA core rails and DSP I/O banks. For FPGAs with higher core current requirements, a parallel power stage or a dedicated switching regulator may be needed to supplement the LDO.

What is the minimum input voltage MCP1827S-1802E/AB needs to maintain a regulated 1.8 V output?

The MCP1827S-1802E/AB requires a minimum input voltage of 2.44 V to begin regulation at the 1.8 V output, based on its nominal dropout of 0.33 V plus the 1.8 V output level. With a maximum dropout of 0.6 V, the input must stay at or above approximately 2.4 V under worst-case load and temperature conditions to maintain full regulation.

Why is the TO-220-3 package of MCP1827S-1802E/AB advantageous for high-current lab bench and prototype boards?

The TO-220-3 package allows the MCP1827S-1802E/AB to be mounted with a standard TO-220 heatsink using a single screw, enabling thermal management of dissipation levels that would be impractical with small SMT packages. Through-hole insertion also simplifies board rework and component replacement on evaluation and prototype boards during early development phases.

What is the RoHS compliance status of MCP1827S-1802E/AB, and is it suitable for export to EU markets?

The MCP1827S-1802E/AB carries a RoHS-compliant lead-free designation, confirming it meets EU RoHS directive requirements for restricted hazardous substance content. This makes it suitable for sale and installation in EU markets and for inclusion in products requiring full RoHS compliance documentation throughout the bill of materials.
