ORDERING INFORMATION Part Number* Package Top Marking MP2143DJ TSOT23-8 See Below * For Tape & Reel, add suffix –Z (e.g. MP2143DJ–Z); For RoHS compliant packaging, add suffix –LF (e.g. MP2143DJ–LF–Z) TOP MARKING ACE: product code of MP2143DJ; Y: year code; PACKAGE REFERENCE TOP VIEW 4 3 2 1 8 7 6 5 PG VIN SW PGND EN FB AGND OUT SOT23-8 ABSOLUTE MAXIMUM RATINGS (1) Supply Voltage VIN ......................................... 6V VSW...................................................................... -0.3V (-5V for < 10ns) to VIN+0.3V (10V for <10ns) All Other Pins.................................-0.3V to +6 V Junction Temperature...............................150°C Lead Temperature ....................................260°C Continuous Power Dissipation (TA = 25°C) (2) ……….….. ............................................... 1.25W Storage Temperature............... -65°C to +150°C Recommended Operating Conditions (3) Supply Voltage VIN ..........................2.5V to 5.5V Output Voltage VOUT................. 0.6V to VIN -0.5V Operating Junction Temp. (TJ). -40°C to +125°C Thermal Resistance (4) θJA θJC TSOT23-8.............................. 100 ..... 55... °C/W Notes: 1) Exceeding these ratings may damage the device. 2) The maximum allowable power dissipation is a function of the maximum junction temperature TJ (MAX), the junction-to- ambient thermal resistance θJA, 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. 3) The device is not guaranteed to function outside of its operating conditions. 4) Measured on JESD51-7, 4-layer PCB. |
