5.2 Output Load Transients

Figure 5-2 shows the load transient response (Chan 2 VOUT, red) for a load step transient from 1 mA to 500 mA (Chan 4 VIN, purple). The TPS7H1210EVM was operating at stock configuration with VIN = –6 V, VOUT = –5 V. Figure 5-2 shows the load transient from 500 mA to 1 mA.
