The q denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°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.
