Output capacitor
Soft start/bypass capacitor
2.2 μF Output Capacitor. Required for stability and transient performance.
10 nF Soft Start Capacitor (ADP1712 Fixed Version) or 10 nF Bypass Capacitor
(ADP1713). Soft start capacitor determines VOUT ramp-up time during startup.
Bypass capacitor reduces output noise and improves PSRR.
R1, R23
J1
Output voltage adjust resistors
Jumper
External Resistors. Used to set VOUT with the ADP1712 adjustable version.
Jumper. Connects EN to IN for automatic startup.
1 Component varies depending on the evaluation board type ordered.
2 Present only on boards with ADP1712 fixed output devices and ADP1713.
3 Present only on boards with ADP1712 adjustable output devices.
