Dropout Voltage

The TPS735-Q1 family of devices uses a PMOS pass transistor to achieve low dropout. When (VIN – VOUT) is less than the dropout voltage (VDO), the PMOS pass device is in the linear region of operation and the input-to-output resistance (R(IN/OUT)) of the PMOS pass element. VDO scales with the output current because the PMOS device behaves like a resistor in dropout.

As with any linear regulator, PSRR and transient response are degraded when (VIN – VOUT) approaches dropout. This effect is shown in the Typical Characteristics section (see Figure 8 through Figure 10).
