Note 1. Output voltage line regulation is defined as the change in output voltage from the nominal value due to change in the
input line voltage.
Note 2. Output voltage line regulation is defined as the change in output voltage from the nominal value due to change in the
bias line voltage.
Note 3. Output voltage load regulation is defined as the change in output voltage from the nominal value due to change in
load current. Regulation is measured at constant junction temperature by using a 10ms current pulse. Devices are
tested for load regulation in the load range from 10mA to 2.0A
Note 4. IGND = IBIAS + (IIN – IOUT). The total current drawn from the supply is the sum of the load current plus the ground
current.
Note 5. When POK pin is applied to VBIAS through the resistor R3, IGND2 should be added to the bias current (VBIAS - VPOK ) / R3.
