Note 1. Maximum positive supply voltage of 60V must be of limited duration (<100msec) and duty cycle(1%). The maximum continuous  
supply voltage is 26V.  
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, TJTJ Max.  
Note 9. Comparator thresholds are expressed in terms of a voltage differential at the Adjust terminal below the nominal reference voltage  
measured at. 6V input. To express these thresholds in terms of output voltage change, multiply by the error amplifier gain = VOUT  
/
VREF = (R1 +R2)/R2. For example, at a programmed output voltage of 5V, the Error output is guaranteed to go low when the  
output drops by 95mV x 5V/ 1.240V - 384mV. Thresholds remain constant as a percent of VOUT as VOUT is varied, with the dropout  
warining occurring at typically 5% below nominal, 7.7% guaranteed.  
Note 10. VEN 0.8V and VIN 26V, VOUT =0.  
Note 11. When used in dual supply system where the regulator load is returned to a negative supply, the output voltage must be diode  
clamped to ground.
