LM150QML March 2006 LM150QML 3-Amp 3-Amp Adjustable RegulatorsGeneral Description differential voltage, supplies of several hundred volts can beregulated as long as the maximum input to output differential The LM150 adjustable 3-terminal positive voltage regulator is not exceeded, i.e., avoid short-circuiting the output. Adjustable is capable of supplying in excess of 3A over a 1.2V to 33V By connecting a fixed resistor between the adjustment pin output range. It is exceptionally easy to use and requires and output, the LM150 can be used as a precision current only 2 external resistors to set the output voltage. Further, regulator. Supplies with electronic shutdown can be both line and load regulation are comparable to discrete achieved by clamping the adjustment terminal to ground designs. Also, the LM150 is packaged in standard transistor which programs the output to 1.2V where most loads draw package which is easily mounted and handled. little current. In addition to higher performance than fixed regulators, theLM150 offers full overload protection available only in IC s. Features Regulators Included on the chip are current limit, thermal overload pro-tection and safe area protection. All overload protection cir- n Adjustable output down to 1.2V cuitry remains fully functional even if the adjustment terminal n Guaranteed 3A output current is accidentally disconnected. n Guaranteed thermal regulation Normally, no capacitors are needed unless the device is n Output is short circuit protected situated more than 6 inches from the input filter capacitors in n Current limit constant with temperature which case an input bypass is needed. An output capacitor n 86 dB ripple rejection can be added to improve transient response, while bypass-ing the adjustment pin will increase the regulator s ripple Applications rejection. n Adjustable power supplies Besides replacing fixed regulators or discrete designs, theLM150 is useful in a wide variety of other applications. Since n Constant current regulators the regulator is "floating" and sees only the input-to-output n Battery chargers Ordering Information NS Part Number JAN Part Number NS Package Number Package Description LM150K/883 5962­8767501XA K02C 2LD T0­3 Metal Can © 2006 National Semiconductor Corporation DS201557
