• Manufacturer Part Number: SPX29300
• Description: (SPX29300 - SPX29303) 3A High Current / Low Dropout Voltage Regulator Adjustable & Fixed Output / Fast Response Time
• Manufacturer: Sipex Corporation

NOTES:
Note 1: Maximum positive supply voltage of 20V must be of limited duration (<100ms) and duty cycle of less than 1%. The maximum continuous supply
Note 2: Full load current (I
Note 3: Dropout voltage is defined as the input to output differential when the output voltage drops to 99% of its nominal value.
Note 4: 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 to the ground 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 time T after a change in power dissipation is applied, excluding load / line regulation effects.
Note 8: V
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
