(1) Pulse-testing techniques are used to maintain the junction temperature as close to the ambient temperature as possible. Thermal effects
must be taken into account separately. All characteristics are measured with a 0.1- µ F capacitor across the input and a 10- µ F capacitor,
with equivalent series resistance of less than 0.4 Ω , across the output.

(1) Pulse-testing techniques are used to maintain the junction temperature as close to the ambient temperature as possible. Thermal effects
must be taken into account separately. All characteristics are measured with a 0.1- µ F capacitor across the input and a 10- µ F capacitor,
with equivalent series resistance of less than 0.4 Ω , across the output.
The TL750L, TL751L series are low-dropout regulators. This means that capacitance loading is important to the
performance of the regulator because it is a vital part of the control loop. The capacitor value and its equivalent
series resistance (ESR) both affect the control loop and must be defined for the load range and temperature
range. Figure 1 shows the recommended range of ESR for a given load with a 10- µ F capacitor on the output.
