8 Applications and Implementation

Note

Information in the following applications sections is not part of the TI component specification,

and TI does not warrant its accuracy or completeness. TI’s customers are responsible for

determining suitability of components for their purposes, as well as validating and testing their design

implementation to confirm system functionality.

8.1 Application Information

The LP5912-EP is designed to meet the requirements of RF and analog circuits by providing low noise,

high PSRR, low quiescent current, and low line or load transient response. The device offers excellent noise

performance without the need for a noise bypass capacitor and is stable with input and output capacitors with

a value of 1 μF. The device delivers this performance in an industry standard WSON package, which for this

device is specified with an operating junction temperature (TJ) of –55°C to +125°C.

8.2 Typical Application

Figure 8-1 shows a typical application circuit for the LP5912-EP. Input and output capacitances may need to be

increased above the 1-μF minimum for some applications.
