Note 2: Full Load current (IFL) is defined as 1.5A.
Note 3: Dropout voltage is defined as the input-to-output differential when the output voltage drops to 99% of its nominal value with
VOUT to VIN
Note 4: VIN = VOUT (nominal) + 1V. For example, use VIN = 4.3V for a 3.3V regulator or use 6V for a 5V regulator. Employ pulse
testing procedures to minimize temperature rise.
Note 5: 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 6: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
Note 7: Thermal regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied,
excluding load or line regulation effects. Specifications are for a 200mA load pulse at VIN = 20V (a 4W pulse) for T = 10ms.
Note 8: VREF ≤ VOUT ≤ (VIN -1V), 2.3V ≤ VIN ≤ 26V, 10mA ≤ IL ≤ IFL, TJ ≤ TJ MAX.
Note 9: VEN ≤ 0.8V and VIN ≤ 26V, VOUT=0
Note 10: When used in dual supply systems where the regulator load is returned to a negative supply, the output voltage must be
diode clamped to ground.
