3 / 26 page formula: If power dissipation exceeds the maximum specified above, the internal thermal protection LM2733 www.ti.com SNVS209F – NOVEMBER 2002 – REVISED DECEMBER 2014 5 Pin Configuration and Functions 5-Pin SOT-23 Package Top View Pin Functions PIN I/O DESCRIPTION NAME NO. SW 1 O Drain of the internal FET switch. GND 2 GND Analog and power ground. FB 3 I Feedback point that connects to external resistive divider. SHDN 4 I Shutdown control input. Connect to VIN if this feature is not used. VIN 5 I Analog and power input. 6 Specifications 6.1 Absolute Maximum Ratings (1) (2) MIN MAX UNIT Input Supply Voltage (VIN) −0.4 14.5 V FB Pin Voltage −0.4 6 V SW Pin Voltage −0.4 40 V SHDN Pin Voltage −0.4 VIN + 0.3 V Power Dissipation(3) Internally Limited Lead Temp. (Soldering, 5 sec.) 300 °C Tstg Storage temperature −65 150 °C (1) Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating the device outside of the limits set forth under the operating ratings which specify the intended range of operating conditions. (2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications. (3) The maximum power dissipation which can be safely dissipated for any application is a function of the maximum junction temperature, TJ(MAX) = 125°C, the junction-to-ambient thermal resistance for the SOT-23 package, θJ-A = 265°C/W, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature for designs using this device can be calculated using the circuitry will protect the device by reducing the output voltage as required to maintain a safe junction temperature. 6.2 ESD Ratings VALUE UNIT Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins(1) ±2000 V(ESD) Electrostatic discharge V Machine model ±200 (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
