TYPICAL PERFORMANCE
Figure 2. LDO_C line transient for 1 V change at supply voltage.
Figure 5. LDO_A load transient response to maximum output
current with 10 µs steps (IOUT max 100 mA).
NOTE: With 135 mA current the overshoot values and lengths
will grow by 30% compared to 100 mA current.
Figure 3. Regulator output noise density.
Figure 6. LDO_B load transient response to maximum output
current with 10 µs steps.
Figure 4. Regulator output voltage temperature dependency.
Figure 7. LDO_C load transient response to maximum output
current with 10 µs steps.
