• Description: 1.5A ULTRA LOW-DROPOUT REGULATOR
• Manufacturer: GAMMA [Gamma Microelectronics Inc.]

ELECTRICAL CHARACTERISTICS (continued)
Note 1: Maximum positive supply voltage of 60V must be of limited duration (<100msec) and duty cycle ( 1%).
Note 2: Full Load current (I ) is defined as 1.5A for the GM66150 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
Note 4: V = V
Note 5: Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the load 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,
Note 8: V
Note 9: Comparator thresholds are expressed in terms of a voltage differential at the Adjust terminal below the nominal reference
Note 10: V
Note 11: When used in dual supply systems where the regulator load is returned to a negative supply, the output voltage must be
The maximum continuous supply voltage is 26V.
