The SPX29300/01/02/03 are 3A, highly accurate voltage regulators with a low drop out voltage of 550mV dropout (typical) @ 3A. These regulators are specifically designed for low voltage applications that require a low dropout voltage and a fast transient response. They are fully fault protected against over-current, reverse battery, and positive and negative voltage transients. On-Chip trimming adjusts the reference voltage to 1% initial accuracy. Other features in the 5 pin versions include Enable, and Error Flag. The SPX29300/01/02/03 are offered & TO-263 packages. For a 1.5A version, refer to the SPX29150 data sheet.

NOTES: Note 1: Maximum positive supply voltage of 20V must be of limited duration < 1%. The maximum continuous supply voltage is 16V. Note 2: Full load current (IFL) is defined as 3.0A. Note 3: Dropout voltage is defined as the input to output differential when the output voltage drops 99% of its nominal value. Note 4: VIN = VOUT (NOMINAL) +1V. For example, use VIN = 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 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. Specifications for a 200mA load pulse as VIN (a 4W pulse) for = 10ms. Note 8: VREF VOUT 10mA IL IFL, Tj < Tjmax. 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 = VOUT/VREF + R2)/R2. For example, at a programmable output voltage of 5V, the Error output is guaranteed to go low when the output drops = 38mV. Threshold remain constant as a percent of VOUT as VOUT is varied, with the dropout warning occurring at typically 5% below nominal, 7.7% guaranteed. Note 10: VEN 0.8V and VIN 16V, VOUT = 0.
