Overview
The NCP135AMT040TBG is a 500 mA Low Dropout (LDO) linear regulator produced by onsemi. This device is equipped with an NMOS pass transistor and a separate bias supply voltage (VBIAS), ensuring very stable and accurate output voltage with low noise. It is particularly suited for space-constrained and noise-sensitive applications, such as battery-operated portable equipment and image sensor applications. The NCP135AMT040TBG is available in a WDFN6 2 mm x 2 mm package, making it ideal for compact designs.
