onsemi NCP145
The NCP145 is a 500 mA VLDO equipped with NMOS pass transistor and a separate bias supply voltage (VBIAS). The device provides very stable, accurate output voltage with low noise suitable for space constrained, noise sensitive applications. The XDFN4 1.2 mm x 1.2 mm package is optimized for use in space constrained applications.| Part No. | NCP145 |
