Manufacturer: Description: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 26V. Note 2: Full load current (IFL) is defined as 1.25A for the LM2941. 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 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 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 26V, 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 remains 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 26V, VOUT = 0. |
