DESCRIPTION
The SPX29150/51/52/53 are 1.5A, highly accuracy voltage regulators with a low drop out
voltage of 390mV dropout (typical) @ 1.5A. 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 SPX29150/51/52/53 is offered in 3 & 5-pin TO-220 & TO-263 packages. For a 3A version,
refer to the SPX29300 data sheet.

NOTES:
Note 1: Dropout voltage is defined as the input to output differential when the output voltage drops to 99% of its nominal value.
Note 2: VIN = VOUT (NOMINAL) +1V. For example, use VIN = 4.3V for a 3.3V regulator. Employ pulse-testing procedures to minimize temperature rise.
Note 3: 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 4: 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.
Note 5: 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 = (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 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 6: VEN ≤ 0.8V and VIN ≤ 16V, VOUT = 0.
Note 7: Maximum positive supply voltage of 20V must be of limited duration (<100m_) < 1%. The maximum continuous supply voltage is 16V.
Note 8: VREF≤ VOUT ≤ (VIN-1), 2.5V≤VIN ≤ 16V, 10mA ≤ IL ≤ IFL, Tj < Tjmax.
