DESCRIPTION
The 117 Series regulators are adjustable 3 terminal voltage regulators capable of supplying in excess of 1.5A over an output
voltage range of 1.25V to 40V (HV Series, 60V). The regulators are exceptionally easy to apply requiring only 2 external resistors
to set the output voltage.
Every effort has been made to make these devices easy to use and difficult to damage. Internal current limiting and power
limiting coupled with true thermal limiting prevents damage due to overloads or shorts, even if the regulators are not fastened
to a heat sink.
FEATURES
• 1.5A Output Current Guaranteed
• Internal Thermal Overload Protection
• Output Short Circuit Protected
• Hermetic Ceramic Surface Mount Package
• Screening Options Available
APPLICATIONS
• Adjustable Power Supplies
• System Power Supplies
• Precision Voltage / Current Regulators

The ● denotes the specifications which apply over the full operating temperature range.
(1) Test conditions unless otherwise stated: VIN - VOUT = 5V, IOUT = 0.5A, PMAX = 20W, IMAX = 1.5A
(2) Regulation is measured at constant junction temperature, using pulse testing at a low duty cycle. Changes in output voltage due to heating
effects are covered under thermal regulation specifications. Load regulation is measured at the junction of the wide and narrow portion of
the output lead.
(3) VMAX = 40V for LM117, IP117, LM117A, IP117A
