Output Capacitor
As with most LDO regulators, the TPS756xx requires an output capacitor connected between OUT and GND to
stabilize the internal control loop. The minimum recommended capacitance value is 47 μF with an ESR
(equivalent series resistance) of at least 200 m
. As shown in Figure 29, most capacitor and ESR combinations
with a product of 47e-6 x 0.2 = 9.4e-6 or larger will be stable, provided the capacitor value is at least 47 μF. Solid
tantalum electrolytic and aluminum electrolytic capacitors are all suitable, provided they meet the requirements
described in this section. Larger capacitors provide a wider range of stability and better load transient response.

APPLICATION INFORMATION (continued)
This information along with the ESR graphs, Figure 19, Figure 20, and Figure 29, is included to assist in
selection of suitable capacitance for the user's application. When necessary to achieve low height requirements
along with high output current and/or high load capacitance, several higher ESR capacitors can be used in
parallel to meet these guidelines.
