Voltage regulator quality indicators for regulated power supplies
(1) voltage regulation rate SV
Voltage adjustment rate is an important indicator to characterise the performance of voltage regulator voltage regulator, also known as the stability factor or stability factor, it characterises when the input voltage VI changes in the regulator output voltage VO stable degree of output voltage is usually a unit of output voltage under the relative change in the input and output voltage of the percentage of said.
(2)Current adjustment rate SI
Current adjustment rate is to reflect the load capacity of the regulator is a major self-indicator, also known as the current stability factor. It characterises when the input voltage is unchanged, the regulator of the load current (output current) due to changes in the output voltage caused by the fluctuation of the inhibition of the ability to change the load current in the specified conditions of the load current change, usually to the unit output voltage under the output voltage changes in the value of the white ratio of the regulator's current adjustment rate ().
(3) Ripple rejection ratio SR
Ripple rejection ratio reflects the regulator on the input side of the introduction of the utility voltage suppression ability, when the regulator input and output conditions remain unchanged, the regulator's ripple rejection ratio is often input ripple voltage peak-to-peak and the output ripple voltage peak-to-peak ratio, generally expressed in decibels, but sometimes can also be expressed in percentage, or directly with the ratio of the two expressed.
(4) temperature stability
Temperature stability of the integrated regulator is based on the specified regulator operating temperature Ti maximum change range (Tmin ≤ Ti ≤ Tmax) regulator output voltage of the relative change in the percentage value () / ΔT.
