An adjustable 3-terminal negative voltage regulator capable of supplying 1.5A over a range of 1.2V to 37V. It is exceptionally easy to use & requires only two external resistors to set the output voltage. Besides having a higher performance compared with fixed regulators the LM337 offers full overload protection with current limiting thermal overload protection & safe area protection. All overload protection circuitry remains fully functional even if the adjustment terminal is disconnected. The adjustment terminal can be bypassed with a capacitor to ground to achieve very high ripple rejection ratios that are difficult to achieve with standard 3-terminal regulators. Output voltage is set by connecting a twin resistor divider between output & circuit ground & connecting the adjustment pin to the junction. A precision current regulator can also be made by connecting a fixed resistor only between the adjustment & output pins & connecting the load to the adjustment pin. The device is available in TO220 package LM337T. Specifications Output voltage 1.2V to 37 V Inputoutput differential voltage 40V max.

A low power quad version of the 741 op-amp featuring high gain & internal compensation with a total supply current requirement for the IC that is less than a single conventional 741. Each op-amp has a class AB output stage & so has virtually no crossover distortion. Additional features include a low input offset voltage 1m V low input offset current typically 4n A low input bias current typically 30n A & a unity gain bandwidth of 1 M Hz. Channel separation is 120d B with a maximum operating voltage of plusmn 18 Vdc. ...

A precision integrated circuit with an output voltage that is linearly proportional to the Centigrade temperature. The advantage over the LM335Z is that it is not necessary to subtract a large constant voltage from the output to obtain the Centigrade scale. The chip does not require any external calibration to achieve accuracies of plusmn 410 deg C at room temperature & plusmn 810deg C over full temperature range. The device draws only 56micro A from voltage supplies in the range 4V to 30V so it has very low self-heating lt 0.1deg C in still air. The LM35DZ oerates in the range 0 C to 100 C. Specifications Oerating range 0deg C to 100deg C plusmn 0.9deg C Non-linearity 0.2deg C Sensor slope 10m Vdeg C Load regulation 0.4m Vm A Line regulation 0.01m Vm A Quiescent current 56micro A at VS 5V56.2micro A at VS 30 V Temperature co-efficient ofquiescent current 0.39micro Adeg C Output impedance 0.1micro with 1m A load ...

A power-amp designed for use in low voltage especially battery-operated applications such as AM-FM radios portable tape cassettes intercoms power invertors etc. For minimum parts count C1 & C2 can be omitted. With pins 1 & 8 open circuit the gain is internally set to 20d B. With a 10micro F capacitor between pins 1 & 8 the gain is increased to 200d B & the gain can be set to anything between these limits by placing a resistor in series with this capacitor. For example a 1k 2 resistor here sets the gain to 50d B. The capacitor on pin 7 sets the power supply rejection ratio from 6d B with no connection to 50d B at 1k Hz with 10micro F. The inputs are referenced to ground while the output is automatically biased to half the supply voltage. Specifications Maximum supply voltage 15 Vdc Quiescent current 4m A Output power with 8 Omega load 325m W 6V supply THD at 125m W with 8 Omega load 0.2 6V supply Bandwidth 300k Hz Input resistance 50k Omega ...

An LED driver that will sequentially light ten LEDs when a gradually increasing voltage is applied to pin 5 dot mode or in bar mode all LEDs indicating voltages below input are lit. In dot mode there is a slight overlap so that at no point are all LEDs extinguished. A brightness control will set LED current between 2m A & 30m A. The drivers are stackable & displays with 100 or more LEDs are possible. Supply voltage 3V to 18V. The driver that sets the indication points can be referenced to a wide range of voltages. The LM3914 is available with linear steps. ...

An independent precision voltage comparator designed specifically to operate from a single power supply over a wide range of voltages. Operation from split rails is possible & the low power supply current drain is independent of the magnitude of the power supply voltage.
