External Oscillator Input (OSC IN ) rise and fall times between 10 ns and 10 μs were determined during device
characterization testing. Signal levels between 0.8V and 2.0V with rise and fall times measured between 10% and 90%
of maximum and minimum values. Not production tested. Additional timing specifications were fully characterized and
specified that are not production tested.
The minimum V IN must meet two conditions: V IN ≥ 3.5V and V IN ≥ (V OUT(MAX) + V DROPOUT(MAX) ).
TCV OUT = (V OUT-HIGH - V OUT-LOW ) *10 6 / (V R * Δ Temperature), V OUT-HIGH = highest voltage measured over the
temperature range. V OUT-LOW = lowest voltage measured over the temperature range.
Load regulation is measured at a constant junction temperature using low duty cycle pulse testing. Changes in output
voltage due to heating effects are determined using thermal regulation specification TCV OUT .
Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its measured
value with an applied input voltage of V OUT(MAX) + V DROPOUT(MAX) or 3.5V, whichever is greater.
