LM317LMXNOPB

The LM317L-N is an adjustable positive voltage
regulator capable of supplying 100 mA over a 1.2-V
to 37-V output range. The LM317L-N is easy to use
and requires only two external resistors to set the
output voltage. Both line and load regulation are
better than standard fixed regulators. The LM317L-N
is available packaged in a standard, easy-to-use
TO-92 transistor package.
The LM317L-N offers full overload protection.
Included on the chip are current limit, thermal
overload protection, and safe area protection.
Normally, no capacitors are required unless the
device is situated more than 6 inches from the input
filter capacitors, in which case an input bypass is
required.
The LM317L-N uses floating topology and sees only
the input-to-output differential voltage, therefore
supplies of several hundred volts can be regulated,
provided the maximum input-to-output differential is
not exceeded. The device makes a simple adjustable
switching regulator, a programmable output regulator,
or by connecting a fixed resistor between the
adjustment and output, the LM317L-N can be used
as a precision current regulator.
The LM317L-N is available in a standard 3-pin TO-92
transistor package, the 8-pin SOIC package, and 6-
pin DSBGA package. The LM317L-N is rated for
operation over a −40°C to 125°C range.
