NOTE 3: Pulse-testing techniques 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-
F capacitor across the input and a 10-F tantalum capacitor
on the output, with equivalent series resistance within the guidelines shown in Figure 3.
PARAMETER MEASUREMENT INFORMATION
The TL751Mxx is a low-dropout regulator. This means that the capacitance loading is important to the performance
of the regulator because it is a vital part of the control loop. The capacitor value and the equivalent series resistance
(ESR) both affect the control loop and must be defined for the load range and the temperature range. Figures 1 and 2
can establish the capacitance value and ESR range for the best regulator performance.
Figure 1 shows the recommended range of ESR for a given load with a 10-
F capacitor on the output. This figure
also shows a maximum ESR limit of 2
and a load-dependent minimum ESR limit.
For applications with varying loads, the lightest load condition should be chosen because it is the worst case. Figure 2
shows the relationship of the reciprocal of ESR to the square root of the capacitance with a minimum capacitance
limit of 10
F and a maximum ESR limit of 2 . This figure establishes the amount that the minimum ESR limit shown
in Figure 1 can be adjusted for different capacitor values. For example, where the minimum load needed is 200 mA,
Figure 2 suggests an ESR range of 0.8
to 2 for 10 F. Figure 2 shows that changing the capacitor from 10 F
to 400
F can change the ESR minimum by greater than 3/0.5 (or 6). Therefore, the new minimum ESR value is 0.8/6
(or 0.13
). This allows an ESR range of 0.13 to 2 , achieving an expanded ESR range by using a larger capacitor
at the output. For better stability in low-current applications, a small resistance placed in series with the capacitor (see
Table 1) is recommended, so that ESRs better approximate those shown in Figures 1 and 2.
