(1)

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is intended to be functional, but does not ensure specific performance limits. For ensured specifications and conditions,

see the Electrical Characteristics.

(2)

If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and

specifications.

(3)

The human body model is a 100 pF capacitor discharged through a 1.5k resistor into each pin. Test method is per JESD22-A114.

(4)

Device power dissipation must be de-rated based on device power dissipation (PD), ambient temperature (TA), and package junction to

ambient thermal resistance (

θJA). Additional heat-sinking may be required to ensure that the device junction temperature (TJ) does not

exceed the maximum operating rating. See the Application Information section for details.

Operating Ratings

(1)

(VOUT + VDO) to VBIAS

0.8V

≤ VOUT ≤ 1.2V

3.0V to 5.5V

VBIAS Supply Voltage

(2)

1.2V < VOUT ≤ 1.8V

4.5V to 5.5V

VEN Voltage

0.0V to VBIAS

IOUT

0 mA to 1.5A

Junction Temperature Range(3)

−40°C to +125°C

(1)

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is intended to be functional, but does not ensure specific performance limits. For ensured specifications and conditions,

see the Electrical Characteristics.

(2)

VIN cannot exceed either VBIAS or 4.5V, whichever value is lower.

(3)

Device power dissipation must be de-rated based on device power dissipation (PD), ambient temperature (TA), and package junction to

ambient thermal resistance (

θJA). Additional heat-sinking may be required to ensure that the device junction temperature (TJ) does not

exceed the maximum operating rating. See the Application Information section for details.
