Figure 1. Start-Up Test Circuit
The TL4050 does not require an output capacitor across cathode and anode for stability. However, if an output
bypass capacitor is desired, the TL4050 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.
The TL4050x-41 is designed to be a cost-effective voltage reference as required in 12-bit data-acquisition
systems. For 12-bit systems operating from 5-V supplies, such as the ADS7842 (see Figure 2), the TL4050x-41
(4.096 V) permits operation with an LSB of 1 mV.
