7 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, as well as validating and testing their design
implementation to confirm system functionality.
7.1 Application Information
The TPS732 LDO regulator uses 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 designed for portable applications. This regulator 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.
7.2 Typical Application
Figure 7-1 shows the basic circuit connections for the fixed-voltage models. Figure 7-2 gives the connections for
the adjustable-voltage version (TPS73201).
