Some voltage-regulator tubes contained small amounts of radionuclides to produce a more reliable ionization. [1] The Corona VR tube is a high-voltage version that is filled with hydrogen at close to atmospheric pressure, and is designed for voltages ranging from 400 V to 30 kV at tens of microamperes.

As linear regulators, the LM317 and LM337 are used in DC to DC converter applications. Linear regulators inherently waste power; the power dissipated is the current passed multiplied by the voltage difference between input and output. A LM317 commonly requires a heat sink to prevent the operating temperature from rising too high. For large ...
In December 2016, Platinum Equity acquired the ENP business from Emerson Electric in a transaction valued in excess of $4 billion. The company was rebranded as Vertiv, and Emerson retained a subordinated equity stake. [12] Vertiv launched as a stand-alone business and appointed Rob Johnson as chief executive officer. [13] [14]
Low-dropout (LDO) regulators operate similarly to all linear voltage regulators.The main difference between LDO and non-LDO regulators is their schematic topology.Instead of an emitter follower topology, low-dropout regulators consist of an open collector or open drain topology, where the transistor may be easily driven into saturation with the voltages available to the regulator.
The smallest n-digit number to achieve this number of primes is 2, 37, 137, 1379, 13679, 123479, 1234679, 12345679, 102345679, 1123456789, 10123456789, ... (sequence A134596 in the OEIS) Primeval numbers can be composite. The first is 1037 = 17×61. A Primeval prime is a primeval number which is also a prime number:
The EMD GP60 is a model of 4-axle diesel-electric locomotive built by General Motors Electro-Motive Division between 1985 and 1994. [1] The GP60 was EMD's first engine that was classified as a "third-generation" locomotive.
