ELECTRICAL CHARACTERISTICS
Unless otherwise specified, Adj V
IN = 2.75 to 7.0V and ADJ IO = 10mA to 3.0A;
Fixed (V
OUT +1.5) to 7.0V and Fixed IO = 0mA to 3.0A
NOTES:
(1) Low duty cycle pulse testing with Kelvin connections required.
(2)
V
OUT, VREF = 1%
(3) Bandwidth of 10 Hz to 10 kHz.
(4) 120 Hz input ripple, (C
ADJ for ADJ = 25F).
(5) Over Temp. (O.T.) = over specified operating junction temperature range.
