Application Hints OUTPUT CAPACITOR Like any low-dropout regulator, the LP2980 requires an out- put capacitor to maintain regulator loop stability. This capac- itor must be selected to meet the requirements of minimum capacitance and equivalent series resistance (ESR) range. It ...

FIGURE 3. 10 μF ESR Range REVERSE CURRENT PATH The internal PNP power transistor used as the pass element in the LP2980 has an inherent diode connected between the regulator output and input. During normal operation (where the input voltage ...
Page 13
Increasing Output Current The LP2980 can be used to control higher-current regulators, by adding an external PNP pass device. With the PNP tran- sistors shown in Figure 6, the output current can be as high as 400 mA, as long ...
Page 14
With limited input voltage range, the LP2980 can control a 3.3V, 3A regulator with the use of a high current-gain external PNP pass transistor as shown in Figure 8. If the regulator loaded with the full 3A, ...
