Frequently Asked Questions
What is the dropout voltage and maximum output current of the MCP1701AT-3002I/CB under load?
The MCP1701AT-3002I/CB has a typical dropout voltage of 400mV at full load and supports up to 250mA output current. This low dropout allows the regulator to maintain 3.0V output from a Li-ion battery down to approximately 3.4V input.
For a battery-powered IoT sensor running from two AA cells, can the MCP1701AT-3002I/CB sustain 3.0V output as the batteries discharge?
Two fresh AA alkaline cells provide about 3V combined, which is below the 4V minimum input of MCP1701AT-3002I/CB, so this part is not recommended for a 2xAA configuration. However, with 3xAA (4.5V fresh) it will regulate at 3.0V with 250mA capability down to roughly 3.4V input before dropout.
How does the MCP1701AT-3002I/CB compare in package size to TO-92 LDO regulators for compact PCB designs?
The MCP1701AT-3002I/CB uses a SOT-23-3 surface-mount package, which occupies significantly less PCB area than through-hole TO-92 packages. SOT-23 measures approximately 3mm x 1.7mm, enabling high-density layouts with automated SMT placement not possible with TO-92 components.
