LM350
3.0 A, Adjustable Output,
Positive Voltage Regulator
The LM350 is an adjustable three?terminal positive voltage
regulator capable of supplying in excess of 3.0 A over an output
2. V out
3. V in
voltage range of 1.2 V to 33 V. This voltage regulator is
exceptionally easy to use and requires only two external resistors to
set the output voltage. Further, it employs internal current limiting,
thermal shutdown and safe area compensation, making it essentially
blow?out proof.
The LM350 serves a wide variety of applications including local,
on card regulation. This device also makes an especially simple
adjustable switching regulator, a programmable output regulator, or
by connecting a fixed resistor between the adjustment and output, the
LM350 can be used as a precision current regulator.
