Frequently Asked Questions
What is the dropout voltage of MCP1702T-3002E/CB and how does it affect battery end-of-life regulation?
The MCP1702T-3002E/CB has a typical dropout voltage of 0.625 V and maximum 0.975 V at 250 mA output current. This low dropout means the 3.0 V output remains regulated until the input falls below about 3.975 V, extending useful battery life compared to standard LDOs with 1.5 V or higher dropout.
Can MCP1702T-3002E/CB regulate from a 9 V battery to 3.0 V for a microcontroller supply rail?
Yes. With a maximum input voltage of 13.2 V, the MCP1702T-3002E/CB accepts a 9 V alkaline battery and delivers a stable 3.0 V at up to 250 mA output, making it a direct drop-in LDO for microcontroller and sensor supply rails that require a regulated 3.0 V from higher-voltage unregulated sources.
How does the SOT-23A-3 package size of MCP1702T-3002E/CB affect PCB layout in compact wearable designs?
The SOT-23A-3 package has a body of 2.9 mm x 1.6 mm with 0.95 mm pin pitch, which is one of the smallest 3-terminal LDO footprints available. This allows the regulator to be placed adjacent to a BLE SoC or MEMS sensor within a 4 mm x 4 mm power management zone on a wearable PCB.
Which compliance certifications does MCP1702T-3002E/CB carry for global component procurement?
MCP1702T-3002E/CB is REACH-compliant and RoHS lead-free certified, as indicated by its Pbfree code. These certifications allow unrestricted sale into EU markets under the RoHS 3 directive and REACH SVHC obligations, reducing customs and environmental compliance burden for volume procurement orders.
