MCP121T-300E/TT

Microchip Technology

The MCP121T-300E/TT is a Microchip voltage supervisory circuit in SOT-23-3 that monitors the supply rail and asserts reset until the voltage crosses the 3.0 V threshold encoded in the '300' of its ordering code. Three leads and a SOT-23 footprint make it one of the smallest ways to give a microcontroller a reliable power-on and brown-out reset in cost-sensitive consumer and industrial products. Selection advice: this is the corrected factory code — strings beginning 'TPMCP121T' carry a distributor prefix and are not Microchip orderable numbers. The TT suffix is the SOT-23 package code; quote the complete MCP121T-300E/TT code. Parameters verified against Microchip Technology documentation.
