CAPACITIVE LOADS

The TLV3201 and TLV3202 feature a push-pull output. When the output switches, there is a direct path between

transition the output current decreases and supply current returns to 40 µA, thus maintaining low power

consumption. Under reasonable capacitive loads, the TLV3201 and TLV3202 maintain specified propagation

delay (see the Typical Characteristics), but excessive capacitive loading under high switching frequencies may

increase supply current, propagation delay, or induce decreased slew rate.
