APPLICATION INFORMATION
output characteristics
All operating characteristics (except bandwidth and phase margin) are specified with 100-pF load capacitance.
The TL03x and TL03xA drive higher capacitive loads; however, as the load capacitance increases, the resulting
response pole occurs at lower frequencies, thereby causing ringing, peaking, or even oscillation. The value of
the load capacitance at which oscillation occurs varies with production lots. If an application appears to be
sensitive to oscillation due to load capacitance, adding a small resistance in series with the load should alleviate
the problem (see Figure 63). Capacitive loads of 1000 pF and larger can be driven if enough resistance is added
in series with the output (see Figure 62).
