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.
An ICD is the umbrella document over the system interfaces; examples of what these interface specifications should describe include: The inputs and outputs of a single system, documented in individual SIRS (Software Interface Requirements Specifications) and HIRS (Hardware Interface Requirements Specifications) documents, would fall under "The Wikipedia Interface Control Document".
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 specification often refers to a set of documented requirements to be satisfied by a material, design, product, or service. [1] A specification is often a type of technical standard. There are different types of technical or engineering specifications (specs), and the term is used differently in different technical contexts.
