Electrical Characteristics
(Continued)
Note 14:
LP2966 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 15:
V
SDT
is the shutdown pin voltage threshold below which the output is disabled.
Note 16:
The condition V
IN
= V
O(NOM)
+ 1V applies when Vout1 = Vout2. If Vout1
≠
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 V
IN
= V
O(NOM)
+ 1V would apply to Vout2 only.
Note 17:
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 18:
The limits for the ground pin current specification, I
GND(0,1)
will be same as the limits for the specification, I
GND(1,0)
.
