When used as a zener dioderesistor combination replacement, the lm78lxx usu ally results in an effective output impedance improvement of two orders of magnitude, and lower quiescent current. This regulator employs internal current limiting, thermal shutdown, and safearea compensation. Fixed voltage regulator an unregulated input voltage v i is filtered by a capacitor c 1 and connected to the ic s in terminal. The ts317 is adjustable 3terminal positive voltage regulator capable of supplying in excess of 1. Careful circuit design has resulted in outstanding load and line regulation. Integrated circuit 3 terminal positive voltage regulator, 5v the nte960 fixed voltage regulator is a monolithic integrated circuit in a to220 type package designed for use in a wide variety of applications including local, on card regulation. Nte electronics nte935 integrated circuit 3 terminal adjustable positive voltage regulator, to 3 package, 5 amp load current, 1. This voltage regulator is exceptionally easy to use and require only two external resistors to set the output voltage. Lm7, lm337n 3terminal adjustable negative regulators. The current depends on the value of the capacitor, the output voltage of the regulator, and the rate at which vin is shorted to ground.
An ic based voltage regulator can be classified in different ways. The lm78lxx series of three terminal positive regulators is available with several fixed output voltages making them useful in a wide range of applications. The lm317 device is an adjustable threeterminal positivevoltage regulator capable of supplying more than 1. They are exceptionally easy to use and require only 2 resistors to set the output voltage. The bypass capacitor on the adjustment terminal can discharge through a low current junction. A common type of classification is 3 terminal voltage regulator and 5 or multi terminal voltage regulator. Lm317 3terminal adjustable regulator datasheet rev. Lm317m threeterminal adjustable output positive voltage. Lmx17hv high voltage threeterminal adjustable regulator. Discharge occurs when either the input, or the output, is shorted. Load and line regulation are specified at constant junction temperature. Threeterminal 5 a adjustable voltage regulators stmicroelectronics. Lm78xxlm78xxa 3terminal 1a positive voltage regulator.
