Linear Voltage Regulator, Adjustable Positive, 35V primary input, 1.2V to 33V, 3A, TO-220-3 - 

The LM350AT/NOPB is a 3-terminal positive Adjustable Regulator capable of supplying in excess of 3A over a 1.2 to 33V output range. This regulator is exceptionally easy to use and require only 2 external resistors to set the output voltage. Further, both line and load regulation are comparable to discrete designs. In addition to higher performance than fixed regulators and offers full overload protection available only in IC's. Included on the chip are current limit, thermal overload protection and safe area protection. All overload protection circuitry remains fully functional even if the adjustment terminal is accidentally disconnected. Normally, no capacitors are needed unless the device is situated more than 6 inches from the input filter capacitors in which case an input bypass is needed. An output capacitor can be added to improve transient response, while bypassing the adjustment pin will increase the regulator's ripple rejection.
