5.5 Electrical Characteristics (continued)

over recommended operating temperature range, TJ = –40°C to +125°C VEN = VIN, VIN = VO(typ) + 1V, IOUT = 1 mA, COUT =

10 µF, CNR = 0.01 µF (Legacy Chip) (unless otherwise noted). All typical values at TJ= 25°C.

(1)

The minimum IN operating voltage is 2.7 V or VO(typ) + 1 V, whichever is greater. The maximum IN voltage is 5.5 V. The maximum

output current is 100 mA.

(2)

If VOUT ≤ 2.5V then VIN(min) = 2.7V, VIN(max) = 5.5V: Line regulation(mV) = (%/V) * VOUT (VIN(max) - 2.7V) / 100 *100

(3)

IN voltage equals VOUT(nom) – 100 mV; The TPS79225 dropout voltage is limited by the input voltage range limitations.
