Positive Adjustable Voltage Regulator, The NTE956 is an adjustable 3-terminal positive voltage regulator in a TO220 type package capable of supplying in excess of 1.5A over a 1.2V to 37V output range. This device is exceptionally easy to use and both line and load regulation are better than standard fixed regulators. In addition to higher performance than fixed regulators, the NTE956 offers full overload protection. 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 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 optional output capacitor can be added to improve transient response. The adjustment terminal can be bypassed to achieve very high ripple rejection ratios which are difficult to achieve with standard 3-terminal regulators. Besides replacing fixed regulators, the NTE956 is useful in a wide variety of other applications. Since the regulator is "floating" and sees only the input-to-output differential voltage, supplies of several hundred volts can be regulated as long as the maximum input-to-output differential is not exceeded. Also, it makes an especially simple adjustable switching regulator, a programmable output regulator, a programmable output regulator, or by connecting a fixed resistor between the adjustment and output, the NTE956 can be used as a precision current regulator. Supplies with electronic shutdown can be achieved by clamping the adjustment terminal to GND which programs the output to 1.2V where most loads draw little current. * Adjustable Output Down to 1.2V * Guaranteed 1.5A Output Current * Line Regulation Typically 0.01%V * Load Regulation Typically 0.1% * Current Limit Constant with Temperature * Eliminates the Need to Stock Many Voltages * Standard 3-Lead Transistor Package Input-Output Voltage Differential, VI - VO Operating Junction Temperature Range, TJ Storage Temperature Range, Tstg Typical Thermal Resistance, Junction-to-Case, RthJC Lead Temperature (During Soldering, 10sec), TL Electrical Characteristics: (Note 1, unless otherwise specified) TA = +25°C, 3V TA = +25°C, 10mA TA = +25°C, 10mA 10mA 10mA /= 5V, Note 2 3V TA = +25°C, 10Hz VOUT = 10V, f = 120Hz, CADJ = 10µF Unless otherwise noted, these specifications apply: 0°C Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle.
