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. NOTES: 1. If load is returned to a negative power supply in a dual supply system, the output must be diode clamped to GND. 2. The PNP pass transistor has a parasitic diode connected between the input and output. This diode is normally reversed bias (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). 3. 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. 4. The package thermal impedance is calculated in accordance with JESD 51-7. recommended operating conditions MIN MAX UNIT VIN Supply input voltage 2.2 16 V VON/OFF ON/OFF input voltage −0.3 VIN V IOUT Output current 150 mA TJ Virtual junction temperature −40 125 °C |
