NOTES:
Note 1: Maximum positive supply voltage of 20V must be of limited duration (<100ms) and duty cycle of less than 1%. The
maximum continuous supply voltage is 16V.
Note 2: Full load current (IFL) is defined as 5A.
Note 3: VIN = VOUT (NOMINAL) +1V. For example, use VIN = 4.3V for a 3.3V regulator. Employ pulse-testing procedures to minimize
temperature rise.
Note 4 Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the load current
plus the ground pin current.
Note 5: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
Note 6: Thermal regulation is defined as the change in output voltage at time T after a change in power dissipation is applied,
excluding load / line regulation effects. Specifications for a 200mA load pulse as VIN = 20V (a 4W pulse) for t = 10ms.
Note 7: VREF≤ VOUT ≤ (VIN-1), 2.3V≤VIN ≤ 16V, 10mA ≤ IL ≤ IFL, Tj < Tjmax.
Note 8: Comparator threshold is expressed in terms of a voltage differential at the Adjust terminal below the nominal reference
voltage measured 6V input. To express these thresholds in terms of output voltage change, multiply the error amplifier gain =
VOUT/VREF = (R1 + R2)/R2. For example, at a programmable output voltage of 5V, the Error output is guaranteed to go low when
the output drops by 95mVx 5V/ 1.240V = 383mV. Threshold remain constant as a percent of VOUT as VOUT is varied, with the
dropout warning occurring at typically 5% below nominal, 7.7% guaranteed.
Note 9: VEN ≤ 0.4V and VIN ≤ 16V, VOUT = 0.
Note 10: Measured with IOUT = IOUT MIN (10mA).
