TIMING
Turn-on delay is defined as the delta between the time that V EN

ADP195
reaches >1.2 V until V OUT rises to ~10% of its final value. The
ADP195 includes circuitry to have typical 5 μs turn-on delay at
the turn-on delay is dependent on the input voltage.

Figure 26. Typical Turn-On Delay Time with Varying Input Voltage
The rise time is defined as the delta between the time from
10% to 90% of V OUT reaching its final value. It is dependent on
the RC time constant where C = load capacitance (C LOAD ) and
R = RDS ON ||R LOAD . Because RDS ON is usually smaller than R LOAD ,
an adequate approximation for RC is RDS ON × C LOAD . An input
or load capacitor is not needed for the ADP195; however, capacitors
can be used to suppress noise on the board. If significant load
capacitance is connected, inrush current is a concern.
