6.5 Electrical Characteristics

Limits apply over T_A = –40°C to +125°C, V_IN = 12 V, V_OUT = 5 V, (unless otherwise noted); C_IN1 = 1 μF, 100-V, 1206 ceramic, C_IN2 = 33 μF, 100-V, electrolytic (optional), and C_OUT = 47 μF, 16-V, 1210 ceramic. Minimum and maximum limits are specified through production test or by design. Typical values represent the most likely parametric norm and are provided for reference only.

(1) The recommended minimum input voltage is 3.0 V or (V_OUT + 1 V), whichever is greater.

(2) The FB pin has both lower and upper thresholds associated with the hysteretic control scheme of the module.

(3) Specified by design. Not production tested.

(4) The overall output voltage tolerance will be affected by the tolerance of the external R_FBT and R_FBB resistors.
