This LDO TLV70028DCKR linear regulator from Texas Instruments acts like a variable resistor to maintain a steady voltage level. This device has a maximum power dissipation of 320 mW. It has an overall accuracy of ±2 %. Its typical dropout voltage at current is 0.043@50mA|0.085@100mA V. This voltage regulation device"s single output can produce a current up to 0.2 A. Use this part at voltages between 2 V and 5.5 V. With a fixed output that has a voltage of 2.8 V, this is power management at its best. A load regulation of 1mV(Typ) and line regulation of 1mV(Typ) is necessary for providing a constant voltage level at your output. Its maximum power dissipation is 320 mW. In order to ensure safe delivery and enable quick mounting of this component after delivery, it will be encased in tape and reel packaging during shipment. Its polarity is positive. This voltage regulation device has an operating temperature range of -40 °C to 125 °C.
