MCP1801T-5002I/OT

Product Overview

The MCP1801T-5002I/OT from Microchip Technology is a surface-mount linear voltage regulator that provides a single fixed positive output of 5V and an output current of 150mA. The device accepts a maximum input voltage of 10V and specifies a dropout voltage of 0.25V at 100mA. It includes an enable control and over-current protection, operates from -40°C to 85°C, and is supplied in a SOT-23-5 package identified as SC-74A, SOT-753.

Key Features

• Fixed positive 5V output from a single regulator channel.
• Maximum input voltage of 10V and output current of 150mA.
• Dropout voltage of 0.25V at 100mA.
• Quiescent current of 50 µA and power-supply rejection of 70dB at 10kHz.
• Enable control and over-current protection.
• Operating temperature range of -40°C to 85°C.
• Surface-mount SOT-23-5 package, also identified as SC-74A, SOT-753.

Applications

• Generating a fixed 5V rail for low-current logic, sensor, or interface circuitry.
• Powering mixed-signal boards where rejection of input ripple at 10kHz is useful.
• Enabling or disabling a 5V output in systems that require controlled rail sequencing.
• Supplying compact surface-mount assemblies where a single-output linear regulator with over-current protection is required.

Design & Procurement Notes

When using the MCP1801T-5002I/OT, confirm that the input supply remains at or below 10V and that sufficient headroom is available above 5V under the intended load. The 0.25V dropout value at 100mA should be considered when selecting the minimum input voltage, while the 150mA output current rating defines the regulated output capability. The enable control can be used to manage the output state, and the device includes over-current protection; operation should remain within the specified -40°C to 85°C range. Layout should match the surface-mount SOT-23-5, SC-74A, SOT-753 package and account for the 50 µA quiescent current and 70dB PSRR at 10kHz in noise-sensitive designs.
