For example, a temperature-controlled circulating bath has two PID controllers in cascade, each with its own thermocouple temperature sensor. The outer controller controls the temperature of the water using a thermocouple located far from the heater, where it accurately reads the temperature of the bulk of the water.

Some manufacturers released some 4000-series equivalent CMOS circuits with a 74 prefix, for example, the 74HC4066 [2] was a replacement for the 4066 with slightly different electrical characteristics (different power-supply voltage ratings, higher frequency capabilities, lower "on" resistances in analog switches, etc.).
The British Ericsson Telephones Limited (ETL), of Beeston, Nottingham (not to be confused with the Swedish TelefonAB Ericsson), original holder of the now-generic trademark Dekatron, used the following system: An initial letter denoting the filling: G – Noble gas-filled; V – Vacuum; One letter denoting the type:
Open source Alternator Regulator suitable for 12v to 48v systems with many different battery chemistries (Lead-Acid, LiFeP04, etc..). Multi stage (3, 4), fully configurable. Features battery voltage and current measurement to assure complete and safe battery charging as well as CAN support for communications with other devices and status output ...
LM317 with heat sink. The LM317 is an adjustable positive linear voltage regulator.It was designed by Bob Dobkin in 1976 while he worked at National Semiconductor. [1]The LM337 is the negative complement to the LM317, which regulates voltages below a reference.
Reference voltage vs free-air temperature at test conditions. Design-center (middle plot) and worst-case deviation of ±2% (upper and lower plots) [ 12 ] The nominal reference voltage, V REF =2.495 V, stated in a datasheet, is tested in zener mode at an ambient temperature of +25 °C (77 °F), and I CA =10 mA.

A voltage regulator module (VRM), sometimes called processor power module (PPM), is a buck converter that provides the microprocessor and chipset the appropriate supply voltage, converting +3.3 V, +5 V or +12 V to lower voltages required by the devices, allowing devices with different supply voltages be mounted on the same motherboard.
