The turn on and off curves are typical, but they look almost identical at all input voltages [36...75 V],
temperatures [-40...+100 °C] and for all models [1.2...2.5 V]. The same curves apply whether the module is
switched using the remote signal or the input voltage.
Figures 15 and 16 show that TXS modules are capable of monotonic start up into loads with very high or
very low impedance without stability problems.
1 The ESR of the 34 x 1 mF Tantalum capacitors is < 0.3 m in total.
