8 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

8.1 Application Information

The TPS732 device belongs to a family of LDO regulators that use an NMOS pass transistor to achieve ultra-

low-dropout performance, reverse current blockage, and freedom from output capacitor constraints. These

features, combined with low noise and an enable input, make the TPS732 ideal for portable applications. This

regulator family offers a wide selection of fixed-output voltage versions and an adjustable-output version. All

versions have thermal and overcurrent protection, including foldback current limit.

8.2 Typical Applications

Figure 31 shows the basic circuit connections for the fixed-voltage models. Figure 32 gives the connections for

the adjustable-voltage version (TPS73201).
