Detailed Description for MCP1824ST-3002E/DB
Product Overview
The Microchip Technology MCP1824ST-3002E/DB is a positive, fixed-output linear voltage regulator designed to supply a single 3V rail at up to 300mA. It is intended for compact surface-mount power paths where a regulated 3V output is required from an input voltage up to 6V. The device specifies a maximum dropout of 0.32V at 300mA and a quiescent current of 220 µA, with 55dB power-supply rejection at 100Hz. Protection features include over-temperature, short-circuit, and under-voltage lockout, and it operates from -40°C to 125°C in a SOT-223-3 package.
Key Features
- Positive fixed 3V output with 300mA output current
- Maximum input voltage of 6V
- Dropout voltage of 0.32V at 300mA
- Quiescent current of 220 µA
- Power-supply rejection ratio of 55dB at 100Hz
- Over-temperature, short-circuit, and under-voltage lockout protection
- Operating temperature range of -40°C to 125°C
- Surface-mount SOT-223-3 package (TO-261-4, TO-261AA)
Applications
- Regulating a fixed 3V rail for digital or analog loads up to 300mA
- Powering compact surface-mount modules where a single-output 3V regulator is required
- Stabilizing a 3V supply in systems with input voltages up to 6V
Design & Procurement Notes
Designers should confirm that the single fixed 3V output and 300mA current capability match the load requirements. The maximum input voltage of 6V and the specified dropout condition at 300mA require adequate headroom in the input supply. The surface-mount SOT-223-3 package supports compact layouts, while the -40°C to 125°C operating range should be considered for environmental margins. The protection features address over-temperature, short-circuit, and under-voltage lockout conditions, but system-level validation should still confirm regulation and protection behavior under actual board conditions.
