e lecTrical characTerisTics The
l
denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. The test conditions are VIN = VOUT + 0.5V, VSHDN = 1.6V, IOUT = 0, CIN = 0.1µF, COUT = 1µF. For LT6657-1.25 VSHDN = 1.45V, CIN = 1µF, COUT = 2.7µF, unless otherwise noted.
