(1)

Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under

which operation of the device is specified. Operating Ratings do not imply specified performance limits. For specified performance limits

and associated test conditions, see the Electrical Characteristics tables.

(2)

All voltages are with respect to the potential at the GND pins.

(3)

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

specifications.

(4)

Internal thermal shutdown circuitry protects the device from permanent damage. Thermal shutdown engages at TJ = 160°C (typ.) and

disengages at TJ = 155°C (typ.).

(5)

The human body model is a 100 pF capacitor discharged through a 1.5 k

Ω resistor into each pin. (MIL-STD-883 3015.7)

2.0V to 4.0V

VIN_C Input Voltage Range (Note: must stay > VOUTLDO + 0.3V)

1.8V to VIN_B

Junction Temperature (TJ) Range

−30°C to +110°C

Ambient Temperature (TA) Range

(3)

−30°C to +85°C

(1)

Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under

which operation of the device is specified. Operating Ratings do not imply specified performance limits. For specified performance limits

and associated test conditions, see the Electrical Characteristics tables.

(2)

All voltages are with respect to the potential at the GND pins.

(3)

In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may

have to be derated. Maximum ambient temperature (TA-MAX) is dependent on the maximum operating junction temperature (TJ-MAX-OP =

110°C), the maximum power dissipation of the device in the application (PD-MAX), and the junction-to ambient thermal resistance of the

part/package in the application (

θJA), as given by the following equation: TA-MAX = TJ-MAX-OP – (θJA × PD-MAX).

THERMAL PROPERTIES

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

specifications.

(2)

Junction-to-ambient thermal resistance is highly dependent on application and board layout. In applications where high maximum power

dissipation exists, special care must be paid to thermal dissipation issues in board design. For more information, please refer to Texas

Instruments' Application Note AN-1112: DSBGA Wafer Level Chip Scale Package (Literature Number SNVA009).
