Frequently Asked Questions
How much dropout voltage does the MCP1826ST-1802E/DB exhibit at full 1 A load?
At full 1 A output current, the MCP1826ST-1802E/DB exhibits a typical dropout voltage of 0.25 V and a maximum of 0.4 V. This low dropout allows the regulator to maintain 1.8 V output from input voltages as low as 2.3 V, which is critical for 2-cell alkaline or Li-ion battery applications where input voltage sags under load.
Can the MCP1826ST-1802E/DB power a 3.3 V microcontroller's 1.8 V I/O supply directly?
Yes. The MCP1826ST-1802E/DB delivers a fixed 1.8 V regulated output at up to 1 A, perfectly matching the I/O supply requirement of many ARM Cortex-M and FPGA devices. With an input range of 2.3 V to 6 V, it can be fed directly from a 3.3 V bus or 5 V rail without a pre-regulator stage.
What PCB footprint does the SOT-223-3 package of the MCP1826ST-1802E/DB require?
The SOT-223-3 package has a body size of approximately 6.5 mm x 3.5 mm with a 2.3 mm pitch between pins and an exposed heat-slug tab. This compact footprint allows single-layer thermal spreading and easily fits on boards as small as a business card, making the MCP1826ST-1802E/DB suitable for handheld device power supplies requiring up to 1 A continuous current.
