DC1729A - LT3086 Demo Board | Low Dropout Linear Regulator, Monitoring & Cable Drop Compensation, 1.55V ≤ VIN ≤ 40V, Vout = 1.0V/1.2V/1.5V/3.3V/5V/12V @ 2.1A

Demonstration circuit 1729A is a 2.1A low dropout adjustable linear regulator featuring the LT®3086. The device is designed with multiple features and operates over a wide 1.4V to 40V input supply range. The LT3086 requires only one resistor to set the output voltage from 0.4V to 32V and it is stable with ceramic output capacitors requiring a minimum of 10μF.
