SNVS665E – JUNE 2010 – REVISED APRIL 2013
Electrical Characteristics
Limits in standard type are for TJ = 25°C only; limits in boldface type apply over the junction temperature (TJ) range of -55°C
to +125°C. Minimum and Maximum limits are ensured through test, design or statistical correlation. Typical values represent
the most likely parametric norm at TJ = 25°C, and are provided for reference purposes only. Unless otherwise stated the
following conditions apply: VIN = 24V, Vout = 3.3V

(1)
Min and Max limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlation
using Statistical Quality Control (SQC) methods. Limits are used to calculate Average Outgoing Quality Level (AOQL).
(2)
Typical numbers are at 25°C and represent the most likely parametric norm.

θJA measured on a 1.705” x 3.0” four layer board, with one ounce copper, thirty five 12 mil thermal vias, no air flow, and 1W power
dissipation. Refer to PCB layout diagrams
