... LP3878 delivers superior performance: Ground Pin Current: Typically 180 µA 100 µA load. Sleep Mode: The LP3878 draws less than 2.0 µA quiescent current when shutdown pin is pulled low. Precision Output: Guaranteed output voltage accuracy room temperature. Basic Application Circuit *Capacitance values shown are minimum required to assure stability, but may be increased without limit ...

... See NS Package Number SDC08A Grade Order Information STD LP3878SD-1.0 STD LP3878SDX-1.0 APPLICATION INFORMATION Optional low noise feature. A small value capacitor connected between BYPASS and GROUND lowers output noise voltage level (100pF - 10nF). DO NOT CONNECT. This pin is used for post package test and should be left floating ...

... LLP package, refer to Application Note AN-1187. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. Note 4: If used in a dual-supply system where the regulator load is returned to a negative supply, the LP3878 output must be diode-clamped to ground. Note 5: The output PNP structure contains a diode between the V on this diode and may induce a latch-up mode which can damage the part (see Application Hints) ...
