Frequently Asked Questions
What is the maximum output current that MCP1826S-3302E/AB can supply continuously?
The MCP1826S-3302E/AB provides up to 1 A continuous output current at a fixed 3.3 V, making it suitable for microcontrollers and RF modules that demand stable high-current 3.3 V supply rails.
How does the 250 mV typical dropout voltage affect its suitability for single-cell Li-ion battery designs?
With only 250 mV typical dropout, the regulator maintains a steady 3.3 V output even when a Li-ion cell drops to approximately 3.58 V, extending usable battery life compared to regulators with 1 V or higher dropout voltage.
What input voltage range does MCP1826S-3302E/AB support, and what is the absolute maximum input voltage?
The device accepts input voltages from 3.7825 V to 6 V for normal operation, with an absolute maximum rating of 6.5 V. Exceeding 6.5 V input risks permanent device damage and loss of regulation.
In which package is MCP1826S-3302E/AB supplied, and what thermal considerations apply?
MCP1826S-3302E/AB comes in a TO-220-3 through-hole package, which enables easy heatsink attachment. At 1 A load, designers should calculate power dissipation as (Vin - 3.3 V) x 1 A and attach an appropriate heatsink to keep junction temperature below 125°C.
