DC330A - LT1761ES5-BYP/SD Demo Board | 2 Circuits: Low Output Noise and Low Current Shutdown, 2.3V ≤ VIN ≤ 20V, Vout = 1.22/1.8/2.0/2.5/2.8/3.0/3.3/5.0V @ 100mA

Demonstration circuit DC330 comprises two low noise micropower voltage regulators using the 100mA output LT®1761 in the 5-lead SOT-23 package. The demo board includes two circuits: one using the LT1761-BYP which allows the internal reference to be bypassed to reduce output voltage noise, and the other using the LT1761-SD which has a low current shutdown feature. Both circuits accept a 2.3V to 20V input and have a jumper-selectable 1.22V/1.5V/1.8V/2.5V/2.8V/3.0V/3.3V/5.0V/Adj output.
