3 / 11 page 3 Date: 5/25/04 SPX29300/01/02/03 3A Low Dropout Voltage Regulator © Copyright 2004 Sipex Corporation at VIN=VOUT + 1V and IOUT = 10mA, CIN = 6.8µF, COUT = 10µF, TA = 25°C, unless otherwise specified. The Boldface applies over the junction temperature range. Adjustable versions are set to 5.0V.

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 to 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 = 20V (a 4W pulse) for t = 10ms. Note 8: VREF≤ VOUT ≤ (VIN-1), 2.3V≤VIN ≤ 16V, 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 = (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 10: VEN ≤ 0.8V and VIN ≤ 16V, VOUT = 0.
