AC Parameters
Thermal Characteristics
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but does not guarantee specific performance limits. For guaranteed specifications and conditions, see the Electrical Characteristics.
Note 2: The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin. Test method is per JESD22-A114.
Note 3: Refer to JEDEC J-STD-020C for surface mount device (SMD) package reflow profiles and conditions. Unless otherwise stated, the temperatures and
times are for Sn-Pb (STD) only.
Note 4: Device operation must be evaluated, and derated as needed, based on ambient temperature (T
junction temperature (T
(EIA/JESD51-3). See POWER DISSIPATION/HEAT-SINKING for details.
Note 5: Line regulation is defined as the change in V
Note 6: Load regulation is defined as the change in V
Note 7: The line and load regulation specification contains only the typical number. However, the limits for line and load regulation are included in the output
voltage tolerance specification.
Note 8: Dropout voltage (V
voltage to drop 2%. For the LP38512-ADJ, the minimum operating voltage of 2.25V is the limiting factor when the programed output voltage is less than typically
1.80V.
