Key Features
- Wide input voltage range from 4.5 V to 55 V supports diverse power-rail applications
- Ultra-low typical dropout voltage of 0.25 V minimizes power dissipation in LDO pass element
- Fixed 4.1 V output in compact 3-lead SOT-23A footprint simplifies layout for space-constrained designs
- High-voltage capability up to 55 V makes it suitable for industrial and automotive supply rails
Applications
The MCP1792T-4102H/CB is ideal for regulating high-voltage supply rails in industrial sensor nodes, automotive ancillary circuits, and telecom equipment where a wide 4.5 V to 55 V input must be stepped down to a stable 4.1 V output. Its tiny SOT-23A package and minimal external component count simplify designs in space-constrained PCB layouts. The fixed output voltage and low dropout characteristics also suit battery-management and always-on power circuitry.

Frequently Asked Questions
What input voltage range does the MCP1792T-4102H/CB support, and what is its fixed output voltage?
The MCP1792T-4102H/CB operates from a 4.5 V to 55 V input voltage range and delivers a fixed 4.1 V regulated output, making it suitable for industrial and automotive applications with widely varying supply rails.
How low is the dropout voltage of the MCP1792T-4102H/CB compared to typical LDO regulators?
The typical dropout voltage is only 0.25 V, significantly lower than many standard LDOs that often require 0.5 V or more. The maximum dropout is specified at 1.2 V, providing a margin for worst-case conditions across the full operating range.
Which high-voltage industrial or automotive designs benefit most from the MCP1792T-4102H/CB?
Designs powered from 12 V, 24 V, or 48 V industrial bus rails benefit greatly, since this regulator handles up to 55 V input while producing a clean 4.1 V output for microcontrollers, sensors, and analog front-ends without requiring an external pre-regulator stage.
What package does the MCP1792T-4102H/CB use, and how does it affect PCB layout?
It comes in a 3-lead SOT-23A package, one of the smallest standard SMT outlines available, with a footprint under 3 mm x 3 mm. This allows placement in tight board areas and pairs well with just an input and output decoupling capacitor for a complete regulator circuit.
