(Note 9)
Note 1: Output or reference voltage temperature coefficients defined as the worst case voltage change divided by the total temperature range.
Note 2: Unless otherwise specified all limits guaranteed for TJ = 25
oC, VIN = 6V, IL = 100A and CL = 1F. Additional conditions for the 8-pin
versions are feedback tied to 5V tap and output tied to output Sense (VOUT = 5V) and VSHUTDOWN
≤ 0.8V.
Note 3: Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output voltage due to
heating effects are covered under the specification for thermal regulation.
Note 4: Line regulation for the CLM2951 is tested at 150
oC for IL = 1mA. For IL = 100A and TJ = 125oC, line regulation is guaranteed by design
to 0.2%. See typical performance characteristics for line regulation versus temperature and load current.
Note 5: Dropout voltage is defined as the input to output differential at which the output voltage drops 100mV below its nominal value measured
at 1V differential at very low values of programmed output voltage, the minimum input supply voltage of 2V (2.3V over temperature) must be
taken input account.
Note 6: VREF
≤ VOUT ≤ (VIN - 1V), 2.3 ≤ VIN ≤ 30V, 100A ≤ IL ≤ 150mA, TJ ≤ TJMAX.
Note 7: Output or reference voltage temperature coefficient is defined as the worst case voltage change divided by the total temprtature range.
Note 8: Comparator thresholds are expressed in terms of a voltage differential at the feedback terminal below the nominal reference voltage
measured at 6V input. To express these thresholds in terms of output voltage change, multiply by the error amplifier gain = VOUT/VREF =
(R1+R2)/R2. For example, at a programmed output voltage of 5V, the error output is guaranteed to go low when the output drops by 95mV x
5V/1.235 = 384mV. Thresholds remain constant as a percent of VOUT as VOUT is varied, with the dropout warning occurring at typically 5% below
nominal, 7.5% guaranteed.
Note 9: VSHUTDOWN
≥ 2V, VIN ≤ 30V, VOUT = 0, Feedback pin tied to 5V Tap.
Note 10: All typical values are not guaranteed.
