Submit Documentation Feedback

(1)

When the device is connected to external feedback resistors at the FB pin, external resistor tolerances are not included.

(2)

The device is not tested under conditions where VIN > VOUT + 2.5 V and IOUT = 0.5 A because the power dissipation is higher than the

maximum rating of the package. Also, this accuracy specification does not apply on any application condition that exceeds the power

dissipation limit of the package under test.

6.5 Electrical Characteristics

over operating temperature range (TJ = –40°C to +125°C), 1.4 V ≤ VIN ≤ 6.5 V, VOUT(NOM) = 0.8 V, IOUT = 5 mA, VEN = 1.4 V,

CIN = COUT = 10 μF, CNR/SS = CFF = 0 nF, SS_CTRL = GND, and PG pin pulled up to VIN with 100 kΩ (unless otherwise

noted); typical values are at TJ = 25°C
