Frequently Asked Questions
What is the dropout voltage of MCP1726-3302E/SN at full 1 A load?
At full 1 A output current the MCP1726-3302E/SN has a typical dropout voltage of 220 mV and a maximum of 500 mV, meaning the input rail must be at least 3.8 V to maintain the regulated 3.3 V output. This low dropout is well suited for single-cell Li-ion or NiMH battery packs.
Which input voltage range does MCP1726-3302E/SN support in practical USB-powered designs?
MCP1726-3302E/SN accepts input voltages from 3.8 V to 6 V, making it directly compatible with 5 V USB bus power as well as regulated 4.2 V Li-ion outputs. The 6.5 V absolute maximum rating provides margin against USB surge conditions, ensuring reliable 3.3 V regulation for sensitive digital loads.
How does MCP1726-3302E/SN serve portable IoT sensor nodes that need long battery life?
The MCP1726-3302E/SN combines a 220 mV dropout voltage with low quiescent current, allowing a single-cell Li-ion battery to power the 3.3 V rail down to approximately 3.5 V and extending run time by 10–15% compared to higher-dropout regulators. Its 1 A current capability covers typical sensor, MCU, and radio module burst loads without external active components.
What package does MCP1726-3302E/SN use and how does that influence PCB layout?
MCP1726-3302E/SN is available in an SOIC-8 package with 1.27 mm pin pitch, requiring only about 30 mm² of board area. This standard footprint simplifies hand-soldering during prototyping and accommodates automated pick-and-place in volume production with a single small input and output bypass capacitor.
