PIN PIN
Input to the Start-up Regulator. Operating input range is 13V to
100V with transient capability to 105V. For power sources outside of
20 21 VIN Input voltage source
this range, the LM5035 can be biased directly at VCC by an
external regulator.
Exposed Pad, underside of No electrical contact. Connect to system ground plane for reduced

package thermal resistance.
1 NC No connection No electrical contact.
10 NC No connection No electrical contact.
20 NC No connection No electrical contact.
22 NC No connection No electrical contact.
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which
operation of the device is intended to be functional. For ensured specifications and test conditions, see the Electrical Characteristics.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(3) The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin. 2kV for all pins except HB, HO and HS
which are rated at 1.5kV.
