LM340k-12 regulator IC

LM340k-12 regulator IC
Output Current up to 1.5 A
Available in Fixed 5-V, 12-V, and 15-V Options
Internal Thermal Overload, Short-Circuit and SOA
Protection
Available in Space-Saving SOT-223 Package
Output Capacitance Not Required for Stability

The LM340-MIL monolithic 3-pin positive voltage
regulators employ internal current-limiting, thermal
shutdown and safe-area compensation, making them
essentially indestructible. If adequate heat sinking is
provided, they can deliver over 1.5-A 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.
Considerable effort was expended to make the
regulator 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 the
regulator is located far from the filter capacitor of the
power supplyLM340k-12 regulator IC
