illustrate

The LP3879 is an 800 mA fixed output voltage regulator designed to provide high performance, low noise for output voltage applications between 1.0V and 1.2V.

In the process of using the optimized VIP ™ (vertically integrated PNP), the LP3879 provides superior performance:

Ground pin current: Typically 5.5 mA @ 800 mA load, 200 μ A@ 100 μA load.

Low Power Shutdown: The shutdown pin is pulled down when the LP3879 is drawn with less than 10μA quiescent current.

Precision output: Guaranteed output voltage accuracy of 1% at room temperature.

Low noise: Wideband output noise is only 18μV10 nF bypass capacitance (typical).
