ELECTRICAL CHARACTERISTICS  
Limits in standard typeface are for Tj = 25°C, and limits in boldface type apply over the full operating junction temperature  
range. Unless otherwise specified, VIN = VO(NOM) + 1V(1), COUT = 1µF, IOUT = 1mA, CIN = 1µF, VSD1 = VSD2 = VIN.

(1) The condition VIN = VO(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 VIN = VO(NOM)+ 1V would apply to Vout2 only.  
(2) :Typical numbers are at 25°C and represent the most likely parametric norm.  
(3) :Limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlation using  
Statistical Quality Control (SQC) methods. The limits are used to calculate Averaging Outgoing Quality Level (AOQL).  
(4) Output voltage tolerance specification also includes the line regulation and load regulation.  
(5) Output voltage line regulation is defined as the change in output voltage from the nominal value due to change in input line voltage.  
(6) Output voltage load regulation is defined as the change in output voltage from the nominal value when the load current changes from  
1mA to 100mA.  
(7) Output voltage cross regulation is defined as the percentage change in the output voltage from the nominal value at one output when  
the load current changes from 1mA to full load in the other output. This is an important parameter in multiple output regulators. The  
specification for ΔVO1/ΔIOUT2 is equal to the specification for ΔVO2/ΔIOUT1  
.
(8) Dropout voltage is defined as the input to output differential at which the output voltage drops 100mV below the nominal value. Drop-out  
voltage specification applies only to output voltages greater than 2.7V. For output voltages below 2.7V, the drop-out voltage is nothing  
but the input to output differential, since the minimum input voltage is 2.7V.  
(9) The limits for the ground pin current specification, IGND(0,1) will be same as the limits for the specification, IGND(1,0)  
.
(10) At elevated temperatures, devices must be derated based on package thermal resistance. The device in the surface-mount package  
must be derated at θjA = 235°C/W, junction-to-ambient. Please refer to APPLICATIONS INFORMATION: Maximum Current Capability  
for further information. The device has internal thermal protection.  
(11) 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.
