The LM4041 does not require an output capacitor across CATHODE and ANODE for stability. However, if an

output bypass capacitor is desired, the LM4041 is designed to be stable with all capacitive loads.

There is a parasitic Schottky diode connected between pins 2 and 3 of the SOT-23 packaged device. Thus, pin 3

of the SOT-23 package must be left floating or connected to pin 2. Similarly, pin 2 of the SC-70 package also

must be left floating or connected to pin 1.
