C. V+ = 2.7V to 5.5V, RL= 5k, CL = 5pF, Pin 3 (PH) = 0V (2-phase, M = 1) unless otherwise specified. Pin 9 (MOD) is at 0V unless otherwise specified. RSET is defined as a resistor connected from the SET pin to the V+ pin. RMOD is defined as a resistor connected from the MOD pin to the V+ pin. SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS
