Upper Threshold Voltage Device set for 5V (Note 9) 60 40 25 mV Lower Threshold Voltage Device set for 5V (Note 9) 75 95 140 mV Hysteresis Device set for 5V (Note 9) 15 mV ENABLE Input SPX2731/SPX2732 Input Logic Voltage Low (OFF) High (ON) 2.4 0.8 V VEN = 16V 100 600 750 V Enable Pin Input Current VEN = 0.8V 1 2 µA Regulator Output Current in Shutdown (Note 10) 10 500 µA Notes: The Bold specifications apply to the full operating temperature range. Note 1: Maximum positive supply voltage of 60V must be of limited duration (<100msec) and duty cycle.) The maximum continuous supply voltage is 16V. Note 2: Full load current (IFL) is defined as 1.5A for the Note 3: Dropout voltage is defined as the input-to output differential when the output voltage drops to 99% of its nominal value with VOUT + 1V applied to VIN. Note 4: VIN = VOUT (NOMINAL) +1V. For example, use VIN= 4.3V for a3.3V 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 changed divided by the total temperature range. Note 7: 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. Specifications are 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 a 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. |
