NOTES:
The Bold specifications apply to the full operating temperature range.
Note 1: Maximum positive supply voltage of 60V must be of limited duration (<100msec) and duty cycle.) The maximum continuous supply voltage is 16V.
Note 2: Full load current (I
FL
) is defined as 1.5A for the B29150/51/52/53.
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 V
IN
.
Note 4: VIN = V

(NOMINAL)
+1V. For example, use V
IN
= 4.3V for a 3.3V 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 to the ground current.
Note 6: Output voltage temperature coefficient is defined as the worst case voltage changed divided by the total temperature range.
Note 7: Thermal regulation is defined as the change in the 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 as V
IN
= 20V (a 4W pulse) for T = 10ms.

Note 9: 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 = V

REF
= (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 = 38mV. Threshold remains constant as a percent of V
