The q denotes specifications which apply over the 0 ° C to 70 ° C
temperature range.
Note 1: Hysteresis is specified at DC. Output ripple depends on capacitor
size and ESR.
Note 2: The LT1302 operates in a variable frequency mode. Switching
frequency depends on load inductance and operating conditions and may
be above specified limits.
Note 3: Minimum switch current 100% tested. Maximum switch current
guaranteed by design.
