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. (2) If load is returned to a negative power supply, the output must be diode clamped to GND. (3) The PNP pass transistor has a parasitic diode connected between the input and output. This diode normally is reverse biased (VIN > VOUT), but will be forward biased if the output voltage exceeds the input voltage by a diode drop (see Application Information for more details). (4) Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability. (5) The package thermal impedance is calculated in accordance with JESD 51-7. MIN MAX UNIT VIN Supply input voltage 2.2(1) 16 V VON/OFF ON/OFF input voltage 0 VIN V VIN – VOUT Input-output differential 0.7 11 V IOUT Output current 100 mA TJ Virtual junction temperature –40 125 °C (1) Minimum VIN of 2.2 V is needed for proper biasing of LDO control circuitry. 4 Submit Documentation Feedback Copyright © 2004–2008, Texas Instruments Incorporated |
