GND 2 5 2 5 — Ground connection; connect externally to PowerPAD ILIM 5 2 5 2 O External resistor used to set current-limit threshold; recommended 15 kΩ ≤ RILIM ≤ 232 kΩ. IN 1 6 1 6 I Input voltage; connect a 0.1 µF or greater ceramic capacitor from IN to GND as close to the IC as possible. OUT 6 1 6 1 O Power-switch output PowerPAD™ — PAD — PAD — Internally connected to GND; used to heat-sink the part to the circuit board traces. Connect PowerPAD to GND pin externally. Add –1 for Latch-Off version (1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) Voltages are referenced to GND unless otherwise noted. 7 Specifications 7.1 Absolute Maximum Ratings over operating free-air temperature range (unless otherwise noted) (1) (2) MIN MAX UNIT Voltage range on IN, OUT, EN or EN, ILIM, FAULT –0.3 7 V Voltage range from IN to OUT –7 7 V IO Continuous output current Internally Limited Continuous total power dissipation See the Thermal Information Continuous FAULT sink current 0 25 mA ILIM source current 0 1 mA TJ Maximum junction temperature –40 150 °C Tstg Storage temperature –65 150 °C |
