2 / 20 page LM27313 SNVS487D – DECEMBER 2006 – REVISED APRIL 2013 www.ti.com Connection Diagram Figure 1. 5-Lead SOT-23 Package – Top View See Package Number DBV PIN DESCRIPTIONS Pin Name Function 1 SW Drain of the internal FET switch. 2 GND Analog and power ground. 3 FB Feedback point that connects to external resistive divider to set VOUT. 4 SHDN Shutdown control input. Connect to VIN if this feature is not used. 5 VIN Analog and power input. These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. Absolute Maximum Ratings (1) (2) Storage Temperature Range −65°C to +150°C Lead Temp. (Soldering, 5 sec.) 300°C Power Dissipation(3) Internally Limited FB Pin Voltage −0.4V to +6V SW Pin Voltage −0.4V to +30V Input Supply Voltage −0.4V to +14.5V Shutdown Input Voltage (Survival) −0.4V to +14.5V ESD Rating(4) Human Body Model ±2 kV (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is to be functional, but does not ensure specific limits. For ensured specifications and conditions see the Electrical Characteristic table. (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 formula: If power dissipation exceeds the maximum specified above, the internal thermal protection circuitry will protect the device by reducing the output voltage as required to maintain a safe junction temperature. (4) The human body model is a 100 pF capacitor discharged through a 1.5 k Ω resistor into each pin. Test method is per JESD22-A114. 2 Submit Documentation Feedback Copyright © 2006–2013, Texas Instruments Incorporated Product Folder Links: LM27313 |
