製品概要Demonstration circuit 1283 is an ultralow dropout voltage supply using the LTC3025-1 500mA output current linear regulator in a small 2mm x 2mm 6-Pin DFN package. The DC1283A has an input voltage range from 0.9V to 5.5V and has a jumper-selectable output that can be set to 0.8V, 1.2V, 1.5V, 1.8V or a user defined value between 0.4V and 3.6V.
The 0.4V reference of the LTC3025-1 allows the DC1283A to supply power to very low voltage applications. The DC1283A is also an excellent choice for post regulation of step-down switching regulators, combining to create a high efficiency low-noise supply. The DC1283 uses small ceramic capacitors, showing the LTC3025-1's ability to maintain stability with ceramic output capacitors.
