1. Uz - stable voltage It refers to the stable voltage value generated at both ends when the voltage stabilizer passes the rated current.
2. Iz - rated current It refers to the current value passing through the regulator when it generates a stable voltage.
3. Rz - dynamic resistance It refers to the ratio of voltage change and current change at both ends of the voltage stabilizer.
4. Pz - rated power consumption It is determined by the allowable temperature rise of the chip, and its value is the product of the stable voltage Vz and the allowable maximum current Izm
5 ?--- temperature coefficient If the temperature of the stabilizer tube changes, its stable voltage will also change slightly. The relative change of the voltage at both ends of the tube caused by the temperature change of 1 is the temperature coefficient (unit:%/).
