Frequently Asked Questions
What output voltage and maximum current does the NCP603SN250T1G deliver?
NCP603SN250T1G provides a fixed 2.5 V regulated output at up to 300 mA load current. With a typical dropout voltage of 187 mV and a maximum of 275 mV, it maintains regulation from input supplies as low as approximately 2.7 V, making it suitable for single-cell Li-ion and USB-powered designs requiring a stable 2.5 V rail.
How does the enable pin on NCP603SN250T1G support low-power system design?
The enable pin on NCP603SN250T1G allows the host microcontroller or power management IC to shut down the 2.5 V, 300 mA LDO output when downstream circuitry is idle, reducing quiescent current consumption to microamp levels. This is especially valuable in battery-operated IoT sensors and wearables where standby power budget is limited to extend battery life beyond hundreds of hours.
Why choose NCP603SN250T1G over a larger LDO package for a compact PCB?
NCP603SN250T1G is housed in a 5-pin SOT-23 package, one of the smallest standard LDO footprints available, occupying less than 3 mm x 3 mm of board area. For portable consumer devices and wearables where PCB space is limited to single-digit square millimeters per component, the SOT-23 outline offers the 300 mA, 2.5 V regulation needed without the area penalty of DPAK or TO-252 alternatives.
