TA = −40°C to +125°C, unless otherwise specified.
Table 5. Parameter Symbol Min Typ Max Unit
NOMINAL INPUT AND OUTPUT CAPACITOR RATINGS BUCK1, BUCK2 Input Capacitor Ratings CMIN1, CMIN2 4.7 40 µF BUCK1, BUCK2 Output Capacitor Ratings CMIN1, CMIN2 10 40 µF LDO1 Input and Output Capacitor Ratings CMIN3, CMIN4 1.0 µF CAPACITOR ESR RESR 0.001 1 Ω 1 The minimum input and output capacitance should be greater than 0.70 µF over the full range of operating conditions. The full range of operating conditions in the application must be considered during device selection to ensure that the minimum capacitance specification is met. X7R- and X5R-type capacitors are recommended; Y5V and Z5U capacitors are not recommended for use because of their poor temperature and dc bias characteristics. Rev.
