Precautions for Using Method

1.Connect a by-pass capacitor (0.1uF) close to the DLR1112 within 7 mm of the unit lead frame. 2.Connect a by-pass capacitor(30pF) between GND and Vout avoid loading effect.

3. Take proper electrostatic-discharge (ESD) precautions while handling these devices. These devices are sensitive to ESD.
