Description
Application Information

VIN
Input voltage source
Input to the VCC Start-up regulator. Operating input range is 5.5V to 75V. For
power sources outside of this range, the LM25037 can be biased directly at
VCC by an external regulator.
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.

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 guaranteed 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)
COMP, RES are output pins. As such, it is not recommended that external power sources be connected to these pins.
(4)
The human body model is a 100 pF capacitor discharged through a 1.5 k
Ω resistor into each pin. 2kV for all pins.

Electrical Characteristics
Specifications with standard typeface are for TJ = 25°C, and those with boldface type apply over full operating junction
temperature range of
−40°C to + 125°C. VVIN = 12V, VVCC = 10V, RRT1 = 30.1 kΩ, RRT2 = 30.1 kΩ, VUVLO = 3V unless
otherwise stated.

(1)
All limits are guaranteed. All electrical characteristics having room temperature limits are tested during production at TA = 25°C. All hot
and cold limits are guaranteed by correlating the electrical characteristics to process and temperature variations and applying statistical
process control.
(2)
Typical specifications represent the most likely parametric norm at 25°C operation.
