Input range: 1.8V to 5.5V 2 GND Ground 3 EN Enable pin logic input: Low = shutdown, High = normal operation. This pin should not be left floating. 4 NC No internal connection 5 VOUT Regulated output voltage These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. Absolute Maximum Ratings (1) (2) VIN pin: Voltage to GND -0.3V to 6.5V EN pin: Voltage to GND -0.3V to (VIN+0.3V) with 6.5V max Continuous Power Dissipation(3) Internally Limited Junction Temperature (TJ-MAX ) 150°C Storage Temperature Range -65°C to + 150°C Package Peak Reflow Temperature (10-20 sec.) 240°C Package Peak Reflow Temperature (Pb-free, 10-20 sec.) 260°C ESD Rating(4) Human Body Model: 2.0kV Machine Model 200V (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 pin. (3) Internal thermal shutdown circuitry protects the device from permanent damage. Thermal shutdown engages at TJ = 160°C (typ.) and disengages at TJ = 140°C (typ.). (4) The Human body model is a 100pF capacitor discharged through a 1.5k Ω resistor into each pin. The machine model is a 200pF capacitor discharged directly into each pin.
