These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. ‡ All voltage values are with respect to network terminal ground.

For more information, refer to TI technical brief literature number SLMA002. recommended operating conditions MIN MAX UNIT Input voltage, VI¶ (1IN, 2IN) 2.7 10 V Output current for each LDO, IO (Note 1) 0 1.0 A Output voltage range, VO (1OUT, 2OUT) 1.5 5.5 V Operating virtual junction temperature, TJ −40 125 °C ¶ To calculate the minimum input voltage for your maximum output current, use the following equation: VI(min) = VO(max) + VDO(max load). NOTE 1: Continuous current and operating junction temperature are limited by internal protection circuitry, but it is not recommended that the device operate under conditions beyond those specified in this table for extended periods of time. |
