ORDERING INFORMATION Part Number* Package Top Marking MP1494SGJ TSOT-23-8 AEP For Tape & Reel, add suffix –Z (e.g. MP1494SGJ–Z); PACKAGE REFERENCE ABSOLUTE MAXIMUM RATINGS (1) VIN ................................................ -0.3V to 17V VSW .................................................................... -0.3V (-5V for <10ns) to 17V (19V for <10ns) VBST ...................................................... VSW+6V All Other Pins................................ -0.3V to 6V (2) Continuous Power Dissipation (TA = +25°C) (3) ..........................................................1.25W Junction Temperature .............................. 150°C Lead Temperature ................................... 260°C Storage Temperature................. -65°C to 150°C Recommended Operating Conditions (4) Supply Voltage VIN .......................... 4.5V to 16V Output Voltage VOUT.............. 0.8V to VINxDMAX Operating Junction Temp. (TJ). -40°C to +125°C Thermal Resistance (5) θJA θJC TSOT-23-8 ............................ 100 ..... 55... °C/W Notes: 1) Exceeding these ratings may damage the device. 2) About the details of EN pin ’s ABS MAX rating, please refer to Page 10, Enable/SYNC control section. 3) The maximum allowable power dissipation is a function of the maximum junction temperature TJ (MAX), the junction-to- ambient thermal resistance θ JA, and the ambient temperature TA. The maximum allowable continuous power dissipation at any ambient temperature is calculated by PD (MAX) = (TJ (MAX)-TA)/θJA. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. Internal thermal shutdown circuitry protects the device from permanent damage. 4) The device is not guaranteed to function outside of its operating conditions. 5) Measured on JESD51-7, 4-layer PCB. |
