Note 1. Employ pulse-testing procedures to minimize temperature rise
Note 2. Output Voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
Note 3. Dropout Voltage is defined as the input-to-output differential when the Output Voltage drops to 99% of its nominal value with
V+1V applied to VOUTIN. For Output Voltages below 2.3V the Dropout Voltage is the input-to-output voltage differential with the minimum
input voltage being 2.3V. The minimum input operation voltage is 2.3V.
Note 4. GND pin current is the regulator quiescent current. The total current drawn from the source is a sum of the load current plus the
GND pin current.
Note 5. For specified VOUT ≥2.5V.
Note 6. V≤VREFOUT≤(VIN-1V), 2.3V≤VIN≤26V, 10mA≤I≤1.5A, TLJ<TJ MAX.
Note 7. VEN ≤0.8V and VIN ≤26V, V=0
Note 8. 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.
