www.ti.com SNVS994 – JULY 2013 LM140K 3-Terminal Positive Regulator
Check for Samples: LM140K FEATURES DESCRIPTION The LM140K monolithic 3-terminal positive voltage
regulator employs internal current-limiting, thermal
shutdown and safe-area compensation, making them
essentially indestructible. If adequate heat sinking is
provided, they can deliver over 1.0A output current.
They are intended as fixed voltage regulators in a
wide range of applications including local (on-card)
regulation for elimination of noise and distribution
problems associated with single-point regulation. In
addition to use as fixed voltage regulators, these
devices can be used with external components to
obtain adjustable output voltages and currents. 1 2 Complete Specifications at 1A Load
Output Voltage Tolerances of В±4% at Tj = 25В°C
Internal Thermal Overload Protection
Internal Short-circuit Current Limit
Output Transistor Safe Area Protection
P+ Product Enhancement Tested Considerable effort was expended to make the entire
series of regulators easy to use and minimize the
number of external components. It is not necessary to
bypass the output, although this does improve
transient response. Input bypassing is needed only if …
