Output Capacitor
The TL4051 does not require an output capacitor across CATHODE and ANODE for stability. However, if an
output bypass capacitor is desired, the TL4051 is designed to be stable with all capacitive loads.
SOT-23 Pin Connections
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.
