Housed in a SOT-23-6 package, it integrates a 100 mA switch and synchronous rectifier, which eliminates the external Schottky diode typical in simpler boost topologies and improves efficiency at light loads. ## Input range and switching behaviour Switching at 500 kHz, the 100 mA switch current rating sets the practical output current ceiling — at 3.3 V out from a 2.5 V input, expect roughly 60-70 mA continuous before the switch current limit is reached.","metaTitle":"Microchip MCP16251T-I/CH Boost Regulator, 100mA, SOT-23-6","metaDescription":"Microchip MCP16251T-I/CH step-up boost regulator, 100mA switch, 0.82V-5.5V input, adjustable output, 500kHz, SOT-23-6.
