Without a heat sink at an ambient temperature at 50 °C, a maximum power dissipation of (T J-T A)/R θJA = ((125-50)/80) = 0.98 W can be permitted.. In a constant voltage mode with an input voltage source at V IN at 34 V and a desired output voltage of 5 V, the maximum output current will be P MAX / (V IN-V O) = 0.98 / (34-5) = 32 mA.

Moreover, this type of circuit might consume a lot of power to reach to the desired noise and precision specification. [12] Despite these limitations, the band gap voltage reference is widely used in voltage regulators, covering the majority of 78xx, 79xx devices along with the TL431 and the complementary LM317 and LM337.
The general negative feedback arrangement can be implemented by an IC voltage regulator (LM317 voltage regulator on Figure 8). As with the bare emitter follower and the precise op-amp follower above, it keeps up a constant voltage drop (1.25 V) across a constant resistor (1.25 Ω); so, a constant current (1 A) flows through the resistor and the ...
A TPS report ("test procedure specification") is a document used by a quality assurance group or individual, particularly in software engineering, that describes the testing procedures and the testing process.
Front page of a floppy disk controller data sheet (1979) A datasheet, data sheet, or spec sheet is a document that summarizes the performance and other characteristics of a product, machine, component (e.g., an electronic component), material, subsystem (e.g., a power supply), or software in sufficient detail that allows a buyer to understand what the product is and a design engineer to ...
