1) For specification of the output voltage V_Q and the dropout voltage V_dr, see Chapter 5 Voltage Regulator.
2) The output voltage V_Q will follow the input voltage, but is outside the specified range.
For details see Chapter 5 Voltage Regulator.
3) Transient measured directly at the input pin. Not subject to production test, specified by design.
4) The minimum output capacitance requirement is applicable for a worst case capacitance tolerance of 30%.
5) Relevant ESR value at f = 10 kHz.
Note: Within the functional range the IC operates as described in the circuit description. The electrical
characteristics are specified within the conditions given in the related electrical characteristics table.
