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 1.0A for the GM66102 series.
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 + 1V applied 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.

older NPN-pass transistor designs, where the minimum
