ORDERING INFORMATION Part Number* Package Top Marking MP2149GJ TSOT23-8 AHM * For Tape & Reel, add suffix –Z (e.g. MP2149GJ–Z); PACKAGE REFERENCE 1 2 3 4 8 7 6 5 TOP VIEW FB2 SW2 EN1 EN2 FB1 SW1 GND IN TSOT23-8 ABSOLUTE MAXIMUM RATINGS (1) Supply Voltage VIN..................................... 6.5V VSW–0.3V (-3V for<10ns) to 6.5V (7.5V for<10ns) All Other Pins.............................–0.3V to +6.5 V Junction Temperature...............................150°C Lead Temperature ....................................260°C Continuous Power Dissipation (TA = +25°C) (2) ................................................................. 1.25W Recommended Operating Conditions (3) Supply Voltage VIN .............................2.7V to 6V Output Voltage VOUT....................0.608V to 5.5V Operating Junction Temp. ....... -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. |
