Exceeding the absolute maximum ratings may result in permanent damage to the device and/or device malfunction. Operation outside of the
parameters specified in the Electrical Characteristics section is not recommended.
NOTES:
(1) Measured in free convection, mounted on 10mm x 10mm, 2 layer FR4 PCB shown in figure 7 ( for MLPD-UT6 package) and figure 8 ( for SOT23-
5 package) with copper of 1oz for each layer.
(2) Tested according to JEDEC standard JESD22-A114-B.
(3) For SOT23-5 package, the limit of the maximum power dissiption shown in figure 2 may reduce the maximum output current.
Electrical Characteristics
Unless specified: V IN = 5.0V, C IN =10μF, C OUT =10μF; L=2.2μH; -40°C<T A <+85 °C; T J(MAX) =125°C; Unless otherwise noted typical values are T A =+25 °C.
