DC2072A is the datasheet of LT3065 45V, 500mA low noise linear regulator
This guide provides setup instructions for evaluating the LT3065 linear regulator in the DC2072A demonstration circuit. It covers jumper settings, input voltage limits, and output voltage adjustment using resistor R8. The circuit supports adjustable output voltages from 1.176V to 4.85V with 500mA output current and includes power good (PWRGD) functionality.
The guide also includes a parts list, schematic diagram, and safety warnings. It emphasizes precautions such as avoiding hot-plugging, using proper capacitors for stability, and noting that the board is for engineering evaluation only, not commercial use.
| Input Voltage Range | 5.35V to 45V |
|---|---|
| Output Voltage Range | 1.176V to 4.85V |
| Maximum Output Current | 495mA |
| Dropout Voltage | 300mV |
Use resistor R8 with the formula: R8 = (V OUT/0.6-1) • 60.4k.
The PWRGD pin goes high when output voltage exceeds 90% of nominal value and low if it falls below 88.4% for more than 25µs.
