7.3.7 Active Overshoot Pulldown Circuitry

This device has pulldown circuitry connected to V_OUT. This circuitry is a 100-μA current sink, in series with a 5.5-kΩ resistor, controlled by V_EN. When V_EN is below V_EN(LOW), the pulldown circuitry is disabled and the LDO output is in high-impedance mode.

If the output voltage is more than 60 mV above nominal voltage when V_EN ≥ V_EN(LOW), the pulldown circuitry turns on and the output is pulled down until the output voltage is within 60 mV from the nominal voltage. This feature helps reduce overshoot during the transient response.
