DC1622A - LT3032IDE Demo Board | Dual Positive/Negative, Low Noise, Low Dropout Linear Regulator, ±2.3V ≤ VIN ≤ ±20V, Vout = ±1.2/±3.3/±5/±12/±15V @ ±150mA

Demonstration circuit 1622A is a dual 150mA linear regulator featuring the LT®3032. The LT3032 is a dual, positive and negative low dropout linear regulator. Each regulator supplies up to 150mA of output current with a typical 300mV dropout voltage. Each regulator’s quiescent current is low (<3μA total in shutdown) and well-controlled in dropout, making it an excellent choice for battery-powered circuits. A 0.01μF bypass capacitor to each regulator reduces output voltage noise to 20μVRMS (positive regulator)/30μVRMS (negative regulator) over a 10Hz to 100kHz bandwidth. The LT3032 is stable with minimum output capacitor of 2.2μF. The regulators do not require any additional ESR. Internal protection circuitry includes reverse output protection, current limiting and thermal limiting. Each regulator is offered as an adjustable output device with an output voltage range down to the ±1.22V reference voltages.
