... Micropower 800mA Low Noise "Ceramic Stable" Adjustable Voltage Regulator for Applications General Description The LP3878-ADJ is an 800 mA adjustable output voltage reg- ulator designed to provide high performance and low noise in applications requiring output voltages as low as 1.0V. Using an optimized VIP ® (Vertically Integrated PNP) process, the LP3878-ADJ delivers superior performance: Ground Pin Current: Typically 5 ...

... 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-ADJ output must be diode-clamped to ground. Note 5: The output PNP structure contains a diode between the V turn on this diode and may induce a latch-up mode which can damage the part (see Application Hints) ...

... Ohms. If these are used as output capacitors for the LP3878- ADJ, the regulator stability requirements are satisfied important to remember that capacitor tolerance and vari- ation with temperature must be taken into consideration when selecting an output capacitor so that the minimum required amount of output capacitance is provided over the full oper- ating temperature range ...
