For VIN ↑ and VOUT(NOM) ≥ 1.1 V:

VIN = (VOUT(NOM) + 0.5 V) to (VOUT(NOM) + 1.1 V)

VIN trise = 30 µs

For VIN ↑ and VOUT(NOM) < 1.1 V:

VIN = 1.6 V to 2.2 V

VIN trise = 30 µs

For VIN ↓ and VOUT(NOM) ≥ 1.1 V

VIN = (VOUT(NOM) + 1.1 V) to (VOUT(NOM) + 0.5 V)

(1)

The minimum capacitance must be greater than 0.5

μF over full range of operating conditions. The capacitor tolerance must be 30% or

better over the full temperature range. The full range of operating conditions for the capacitor in the application must be considered

during device selection to ensure this minimum capacitance specification is met. X7R capacitors are recommended however capacitor

types X5R, Y5V, and Z5U may be used with consideration of the application conditions.

(2)

This specification is verified by design.
