Overview
The NCP130AMX120TCG is a 300 mA Very Low Dropout (VLDO) linear voltage 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. It is particularly suited for space-constrained, noise-sensitive applications and is optimized for battery-operated portable devices due to its low quiescent current (IQ) consumption. The regulator comes in an XDFN6 package, measuring 1.2 mm x 1.2 mm, which is ideal for compact designs.
