Frequently Asked Questions
What is the output current capability and dropout voltage of the MCP1826T-ADJE/ET?
The MCP1826T-ADJE/ET is rated for up to 1 A continuous output current with a typical dropout voltage of 0.25 V and a maximum of 0.4 V. This low dropout characteristic allows the regulator to maintain a stable output even when the input voltage is only 0.4 V above the desired output, which is advantageous in battery-powered systems where the supply voltage decreases as the battery discharges.
How is the output voltage adjusted on the MCP1826T-ADJE/ET and what range is achievable?
The MCP1826T-ADJE/ET has an adjustable output voltage set by an external resistor divider connected to the ADJ pin. The output voltage can be programmed from approximately 0.8 V up to the input voltage minus the 0.25 V dropout, covering a wide range suitable for powering microcontrollers, FPGAs, memory modules, and RF transceivers with different supply requirements, typically from 1.0 V to 5.0 V depending on the input supply.
In which embedded power supply designs does the MCP1826T-ADJE/ET provide the greatest advantage?
The MCP1826T-ADJE/ET excels in designs where multiple regulated supply voltages are needed from a single input rail, such as microcontroller-plus-RF systems requiring both 3.3 V at 500 mA and 1.8 V at 300 mA from a single Li-ion battery. Its 1 A capability handles peak loads from wireless transmissions or motor-driver activation events, while the 0.25 V dropout ensures the output remains regulated even at 3.6 V battery level delivering 3.3 V output.
What thermal performance does the DDPAK-5 package of the MCP1826T-ADJE/ET provide for high-current operation?
The MCP1826T-ADJE/ET uses a DDPAK-5 (D2PAK) surface-mount package, which includes a large exposed thermal pad bonded to the die for superior heat dissipation compared to SOT-23 or SOIC packages. At 1 A output with a 2 V input-to-output differential, the device dissipates 2 W, and the DDPAK-5 package combined with a proper PCB copper pour can achieve a junction-to-board thermal resistance low enough to sustain continuous 1 A operation within the -40°C to +125°C industrial temperature range.
