Frequently Asked Questions
What is the minimum input-to-output voltage difference required by the MCP1824T-ADJE/DC at full load?
The MCP1824T-ADJE/DC has a maximum dropout voltage of 0.32 V at 300 mA load current, meaning the input supply must be at least 0.32 V above the desired output voltage. At a 3.3 V output, the input voltage needs to be only 3.62 V or higher, making it compatible with a single lithium-ion cell discharging from 4.2 V to approximately 3.7 V.
How is the output voltage of the MCP1824T-ADJE/DC set and what resistor values are needed for a 3.3 V rail?
The MCP1824T-ADJE/DC output voltage is set with a resistor divider from the output to the ADJ pin, referenced to an internal 0.8 V reference. For a 3.3 V output, the ratio requires R1 approximately 3.1 times R2, using standard values such as R1 = 31.6 kOhm and R2 = 10 kOhm, achievable with common 1% tolerance resistors without external capacitors.
For a portable IoT device running from a 3.7 V LiPo battery, how does the MCP1824T-ADJE/DC compare to a switching regulator?
At load currents below 100 mA and an input-to-output differential below 0.5 V, the MCP1824T-ADJE/DC dissipates less than 50 mW, making thermal losses comparable to a switching regulator with 85% efficiency. Its zero switching noise eliminates EMI concerns, simplifying PCB layout for noise-sensitive RF or ADC circuits in IoT devices operating from a 3.7 V LiPo cell.
