3 / 9 page 3 Date:5/25/04 SP29150/51/52/53 1.5A Low Dropout Voltage Regulator © Copyright 2004 Sipex Corporation at V IN=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.

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.
