3 / 11 page 3 Rev:A Date: 3/8/04 SPX29500/01/02/03 5A Low Dropout Voltage Regulator © Copyright 2004 Sipex Corporation ELECTRICAL CHARACTERISTICS: Continued Specifications are at VIN = VOUT + 1V and IOUT = 10mA, CIN = 6.8µF, COUT = 22µF, TA = 25°C, unless otherwise specified. The ♦ denotes the specifications which apply over the full operating temperature range, unless otherwise specified. PARAMETER MIN TYP MAX UNITS CONDITIONS Flag Output (Error Comparator) SPX29501/03 Output Leakage 0.01 1 µAVOH=16V Current 2 ♦ Output Low Voltage 220 300 mV Device set for 5V,VIN=4.5V, IOL=250µA 400 ♦ Upper Threshold 40 60 mV Device set for 5V, (Note 8) Voltage 25 ♦ Lower Threshold 75 95 mV Device set for 5V, (Note 8) Voltage 140 ♦ Hysteresis 15 mV Device set for 5V, (Note 8) Enable Input SPX29501/02 Input Logic Voltage Low (OFF) 0.8 V (Note 10) High (ON) 2.4 ENABLE Input Current 100 600 µAVEN=16V 750 ♦ 0.6 2 µAVEN=0.8V 4 ♦ Regulator Output 10 µA (Note 9) Current in Shutdown 500 ♦ Thermal Resistance 2 °C/W TO-220 Junction to Case, at Tab 60 TO-220 Junction to Ambient 2 TO-263 Junction to Case, at Tab 60 TO-263 Junction to Ambient 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 voltage is 16V. Note 2: Full load current (IFL) is defined as 5A. Note 3: VIN = VOUT (NOMINAL) +1V. For example, use VIN = 4.3V for a 3.3V regulator. Employ pulse-testing procedures to minimize temperature rise. Note 4 Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the load current plus the ground pin current. Note 5: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range. Note 6: 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 7: VREF≤ VOUT ≤ (VIN-1), 2.3V≤VIN ≤ 16V, 10mA ≤ IL ≤ IFL, Tj < Tjmax. Note 8: 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 = 383mV. 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 9: VEN ≤ 0.4V and VIN ≤ 16V, VOUT = 0. Note 10: Measured with IOUT = IOUT MIN (10mA). |
