Overview
The NCP134AMX110TCG is a 500 mA Very Low Dropout (VLDO) CMOS voltage regulator produced by onsemi. This device is designed for space-constrained, noise-sensitive applications and is particularly optimized for battery-operated portable equipment. It features an NMOS pass transistor and a separate bias supply voltage (VBIAS) to ensure stable and accurate output voltage with low noise. The regulator is available in a compact XDFN4 package, measuring 1.2 mm x 1.2 mm x 0.4 mm, making it ideal for applications where space is limited.
