The information provided herein is believed to be reliable; however, BURR-BROWN assumes no responsibility for inaccuracies or omissions. BURR-BROWN assumes
no responsibility for the use of this information, and all use of such information shall be entirely at the user's own risk. Prices and specifications are subject to change
without notice. No patent rights or licenses to any of the circuits described herein are implied or granted to any third party. BURR-BROWN does not authorize or warrant
any BURR-BROWN product for use in life support devices and/or systems.
NOTES: (1) Specification applies over the full operating Junction temperature range, 0
°C to 125°C. (2) REG1117 and REG1117A adjustable versions require a
minimum load current for
±3% regulation. (3) Dropout voltage is the Input voltage minus output voltage that produces a 1% decrease in output voltage.
(4) Percentage change in unloaded output voltage before vs after a 30ms power pulse of IO = 800mA (REG1117 models), IO = 1A (REG1117A), VIN – VO = 1.4V
(Reading taken 10ms after pulse).

ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degrada-
tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.
