LM2990负低压差稳压器 LM2990 Negative Low Dropout Regulator
This LDO linear regulator from Texas Instruments gives you control over the voltage levels of your circuit. It has an overall accuracy of ±5 %. Its typical dropout voltage at current is 0.1@100mA|0.6@1A V. This voltage regulation device"s single output can produce a current up to 1.8Typ A. Supply your circuit with sufficient power by implementing this, which requires a minimum input voltage of -26 V that does not exceed 0.3 V. With a fixed output that has a voltage of -5.2 V, this is power management at its best. At a load regulation of 40mV and line regulation of 40mV your circuit is capable of maintaining a constant voltage level at your output. In order to ensure parts aren"t damaged by bulk packaging, this product comes in tube packaging to add a little more protection by storing the loose parts in an outer tube. The maximum dropout voltage is 0.3@100mA|1@1A V. Its polarity is negative. This voltage regulation device has a minimum operating temperature of -40 °C and a maximum of 125 °C.
