The following graphs show typical electrical characteristics for LDO and Load switch. They have been measured using a 2.2 µF output capacitor, unless mentioned otherwise.

Figure 1. LDO start-up, VOUTLDO=1.8 V


The following two figures show load regulation in various modes for VOUTLDO=1.8 V.

Figure 2. LDO load regulation in High Power mode


Figure 3. LDO load regulation in Ultra-Low Power mode


The following two figures show accuracy over temperature in various modes.

Figure 4. LDO accuracy, High Power mode (load=1 mA)


Figure 5. LDO accuracy, Ultra-Low Power mode (load=0.1 mA)


The following two figures show load transient in High Power mode for various output voltages. Load changes from 1 mA to 40 mA in 10 μs.
