Processor Supervisor 2.625V 3V/3.3V/5V 3-Pin TO-92

The MCP101 is a voltage supervisory device designed to keep a microcontroller in reset until the system voltage has reached the proper level and stabilized. It also operates as protection from brown-out conditions when the supply voltage drops below a safe operating level. MCP100 has a CMOS Push-Pull output with Active Low reset and is available in a choice of seven different trip voltages. It operates over the extended industrial temperature range (-40°C/+85°C). MCP100 is available in a TO-92 or SOT23-3 packages.
