Linear regulator specifications Symbol C Parameter Conditions Value Unit Min Typ Max VMREG CC P Main regulator output voltage Power-up, before trimming, no load 1.12 1.20 1.28 V CC P After trimming, maximum load 1.08 1.18 1.23 IDDMREG CC T Main regulator current provided to VDD_LV domain The maximum current required by the device (IDD_LV) may exceed the maximum current which can be provided by the internal linear regulator. In this case, the internal regulator mode cannot be used. —— — 700 mA IDDCLAMP CC D Main regulator rush current sinked from VDD_HV_IO_MAIN domain during VDD_LV domain loading Power-up condition — — 400 mA ΔIDDMREG (1) CC T Main regulator output current variation 20 µs observation window -200 — 200 mA IMREGINT CC D Main regulator current consumption IMREG = max — — 22 mA DIMREG = 0 mA — — — 1. Internal schemes must be used by the application (for example: frequency ramping feature enabled) to ensure that incremental demands are made on the external power supply within the maximum value. Mbist/Lbist must be configured to avoid exceeding the maximum value. Table 41. Auxiliary regulator specifications Symbol C Parameter Conditions Value Unit Min Typ Max VAUX CC P Aux regulator output voltage After trimming, internal regulator mode 1.08 1.18 1.21 V CC P After trimming, external regulator mode 1.03 1.12 1.16 IDDAUX CC T Aux regulator current provided to VDD_LV domain —— — 250 mA ΔIDDAUX CC T Aux regulator current variation 20 µs observation window —100 — 100 mA IAUXINT CC D Aux regulator current consumption IMREG = max — — 1.1 mA DIMREG = 0 mA — — 1.1 |
