Figure 1. Input Reflected-ripple Test Set-up

Measure input reflected current with a simulated source inductance L1 of 1uH.

Capacitor Cin offsets possible battery impedance. Measure current as shown above.

Figure 2. Peak-to-Peak Output Noise Measurement Test Set-up

Note:

(1) Use C1 = 1uF@50V X7R ceramic capacitor and a 10uF@10V tantalum capacitor.

(2) Use C2 = 2 x 150uF/6.3V special polymer (Panasonic: EEFUE0J151R)

(3) Scope measurement should be made using a BNC socket.
