SNVS488A – JUNE 2007 – REVISED MARCH 2013

Operating Ratings

(1) (2)

Voltage on power pin (VDD)

2.7V to 5.5V

Recommended Load Current

1 mA to 20 mA

Junction Temperature (TJ) Range

-30°C to +125°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 ensured. Operating Ratings do not imply ensured performance limits. For ensured 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 =

125°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

Junction-to-Ambient Thermal Resistance (

θJA)

(1)

87°C/W

(1)

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

dissipation exists, special care must be paid to thermal dissipation issues in board design.
