Conditions

Note 1:

External Oscillator Input (OSCIN) 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 VIN must meet two conditions: VIN ≥ 3.5V and VIN ≥ (VOUT(MAX) + VDROPOUT(MAX)).

TCVOUT = (VOUT-HIGH - VOUT-LOW) *106 / (VR * ΔTemperature), VOUT-HIGH = highest voltage measured over the

temperature range. VOUT-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 TCVOUT.

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 VOUT(MAX) + VDROPOUT(MAX) or 3.5V, whichever is greater.
