LM337-N-MIL100-mA, negative, adjustable linear voltage regulator | Voltage Regulators - Linear, Low Drop Out (LDO) Regulators | 19 | Active | The LM337L is an adjustable 3-pin negative voltage regulator capable of supplying 100 mA over a –1.2-V to –37-V output range. The LM337L is easy to use and requires only two external resistors to set the output voltage. Both line and load regulation are better than standard fixed regulators. The LM337L is packaged in a standard, easy-to-use TO-92 transistor package.
In addition to higher performance than fixed regulators, the LM337L 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 pin is disconnected.
Normally, only a single 1-µF solid tantalum output capacitor is required unless the device is situated more than 6 inches from the input filter capacitors, in which case an input bypass is required. A larger output capacitor can be added to improve transient response. The adjustment pin can be bypassed to achieve very high ripple rejection ratios, which are difficult to achieve with standard 3-pin regulators.
Besides replacing fixed regulators, the LM337L is useful in a wide variety of other applications. Because the regulator isfloatingand monitors 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.
The LM337L makes a simple adjustable switching regulator, a programmable output regulator, or by connecting a fixed resistor between the adjustment and output, the LM337L can be used as a precision current regulator. Supplies with electronic shutdown can be achieved by clamping the adjustment pin to ground, which programs the output to 1.2 V, where most loads draw little current.
The LM337L is available in a standard TO-92 transistor package and a standard SO-8 surface mount package. The LM337L is rated for operation over a –25°C to 125°C range.
For applications requiring output current in excess of 0.5 A and 1.5 A, The LM137 series may be suitable. For the positive complement, the LM117 and LM317L series are options.

LM338-MIL5A Adjustable Output Linear Regulator | Voltage Regulators - Linear, Low Drop Out (LDO) Regulators | 3 | Active | The LM338-MIL series of adjustable 3-terminal positive voltage regulators is capable of supplying in excess of 5 A over a 1.2-V to 32-V output range. They are exceptionally easy to use and require only 2 resistors to set the output voltage. Careful circuit design has resulted in outstanding load and line regulation, comparable to many commercial power supplies. The LM338-MIL family is supplied in a standard 3-lead transistor package.
A unique feature of the LM338-MIL family is time-dependent current limiting. The current limit circuitry allows peak currents of up to 12 A to be drawn from the regulator for short periods of time. This allows the LM338-MIL to be used with heavy transient loads and speeds start-up under full-load conditions. Under sustained loading conditions, the current limit decreases to a safe value protecting the regulator. Also included on the chip are thermal overload protection and safe area protection for the power transistor. Overload protection remains functional even if the adjustment (ADJ) pin 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 increases the ripple rejection of the regulator.
Besides replacing fixed regulators or discrete designs, the LM338-MIL is useful in a wide variety of other applications. Because the regulator is floating and receives 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; do not short-circuit output to ground. The part numbers in the LM338-MIL series which have aKsuffix are packaged in a standard steel TO-CAN package, while those with aTsuffix are packaged in a TO-220 plastic package. The LM338-MIL is rated for TJ= –55°C to 150°C, and the LM338-MIL is rated for TJ= 0°C to 125°C.

LM34±1°F 5V-30V, Analog output temperature sensor with Fahrenheit scale calibration | Analog and Digital Output | 14 | Active | The LM34 series devices are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Fahrenheit temperature. The LM34 device has an advantage over linear temperature sensors calibrated in degrees Kelvin, because the user is not required to subtract a large constant voltage from its output to obtain convenient Fahrenheit scaling. The LM34 device does not require any external calibration or trimming to provide typical accuracies of ±1/2°F at room temperature and ±1-1⁄2°F over a full −50°F to 300°F temperature range. Lower cost is assured by trimming and calibration at the wafer level. The low output impedance, linear output, and precise inherent calibration of the LM34 device makes interfacing to readout or control circuitry especially easy. It can be used with single power supplies or with plus and minus supplies. Because the LM34 device draws only 75 µA from its supply, the device has very low self-heating, less than 0.2°F in still air.
