Description
The LM3940IT-3.3NOPB is a linear voltage regulator belonging to the category of electronic component models. It has a high accuracy of 1.25A and a low dropout voltage of only 40mV at light loads, which makes it ideal for low voltage applications. The device has a low quiescent current of 240µA and faster transient response, which is an excellent choice for powering low voltage applications that require lower voltage dropout. The LM3940IT-3.3NOPB can regulate from +2.5V to 3.8V supplies and can be used as a post-regulator for switching supply applications.
