7.1 Application Information

The TPS732xx-EP belongs to a family of new generation 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 TPS732xx-EP 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 over-current protection, including foldback current limit.

Figure 7-1 shows the basic circuit connections for the fixed voltage models. Figure 7-2 gives the connections for the adjustable output version (TPS73201-EP).

R1 and R2 can be calculated for any output voltage using the formula shown in Figure 7-2. Sample resistor values for common output voltages are shown in Figure 6-2. For the best accuracy, make the parallel combination of R1 and R2 approximately 19 kΩ.
