Key Features
- Fixed 5.0 V output with tight regulation for stable microcontroller and logic supply rails
- 150 mA maximum output current in a compact SOT-23-5 5-pin package
- 200 mV typical dropout voltage enabling efficient regulation from low-headroom supplies
- 6 V to 10 V input range compatible with standard 7.5 V and 9 V wall adapters
- High PSRR for excellent power supply noise rejection in mixed-signal circuits
- Industrial-grade operating temperature range for reliable performance in harsh environments
Applications
MCP1801T-5002I/OT is used to generate a stable 5 V regulated supply for microcontrollers, sensors, and logic circuitry in industrial control modules, IoT gateways, and consumer electronics powered from 9 V or 12 V adapters. Its low dropout of 200 mV preserves efficiency when the unregulated input sags close to 5 V, making it a reliable post-regulator after a buck converter or battery pack. The SOT-23-5 footprint minimizes PCB area for space-constrained boards such as USB hubs, smart plugs, and wireless sensor nodes.

Frequently Asked Questions
What is the dropout voltage of MCP1801T-5002I/OT, and how does it affect minimum usable input voltage for a 5 V output?
MCP1801T-5002I/OT has a typical dropout voltage of 200 mV and a maximum of 250 mV, meaning the input must stay above approximately 5.25 V to maintain a regulated 5.0 V output. This low dropout is advantageous in designs powered from 6 V lead-acid batteries or 9 V adapters where the supply may sag under load, ensuring the output stays in regulation over the full input range of 6 V to 10 V.
For which embedded system supply rails is MCP1801T-5002I/OT's 150 mA output rating adequate?
MCP1801T-5002I/OT delivers up to 150 mA at 5.0 V, which is sufficient for powering 8-bit or 16-bit microcontrollers drawing 20 mA to 50 mA, alongside supporting logic, LEDs, and small sensors. It is well-suited as a local supply for UART level shifters, I2C sensor clusters, or small LCD modules in industrial HMI panels and IoT sensor nodes, where the total 5 V load stays well under 150 mA.
How does MCP1801T-5002I/OT compare with MCP1700-5002E/TT when choosing a 5 V LDO for a 9 V-input design?
MCP1801T-5002I/OT offers a higher 150 mA output current and better PSRR than the MCP1700-5002E/TT, which is rated at 250 mA but targets lower 6 V maximum inputs. For a 9 V-input design up to 10 V absolute, MCP1801T-5002I/OT is the correct choice because it is specified for the full 10 V input range, while also providing improved noise rejection relevant to mixed-signal circuits sharing the 5 V rail.
