Electrical Characteristics (Continued)

Note 16: Output voltage tolerance specification also includes the line regulation and load regulation.

Note 17: LP2966EP has fold back current limited short circuit protection. The knee is the current at which the output voltage drops 10% below the nominal value.

Note 18: VSDT is the shutdown pin voltage threshold below which the output is disabled.

Note 19: The condition VIN = VO(NOM) + 1V applies when Vout1 = Vout2. If Vout1 â Vout2, then this condition would apply to the output which is greater in value.

As an example, if Vout1 = 3.3V and Vout2 = 5V, then the condition VIN = VO(NOM)+ 1V would apply to Vout2 only.

Note 20: Turn-on delay is the time interval between the low to high transition on the shutdown pin to the output voltage settling to within 5% of the nominal value.

Turn-off delay is the time interval between the high to low transition on the shutdown pin to the output voltage dropping below 50% of the nominal value. The external

load impedance influences the output voltage decay in shutdown mode.

Note 21: The limits for the ground pin current specification, IGND(0,1) will be same as the limits for the specification, IGND(1,0).
