2 / 33 page VIN 1 2 3 5 4 EN GND N/C VREF LM4128, LM4128Q SNVS475E – NOVEMBER 2006 – REVISED APRIL 2013 www.ti.com Connection Diagram 5-Pin SOT-23 Package – Top View See Package Number DBV (R-PDSO-G5) PIN DESCRIPTIONS Pin # Name Function 1 N/C No connect pin, leave floating 2 GND Ground 3 EN Enable pin 4 VIN Input supply 5 VREF Reference output 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) Maximum Voltage on any input -0.3 to 6V Output short circuit duration Indefinite Power Dissipation (TA = 25°C) (2) 350 mW Storage Temperature Range −65°C to 150°C (soldering, 10sec) 260°C Lead Temperature Vapor Phase (60 sec) 215°C Infrared (15sec) 220°C ESD Susceptibility(3) Human Body Model 2 kV (1) Absolute Maximum Ratings indicate limits beyond which damage may occur to the device. Operating Ratings indicate conditions for which the device is intended to be functional, but do not ensure specific performance limits. For ensured specifications, see Electrical Characteristics. (2) Without PCB copper enhancements. The maximum power dissipation must be de-rated at elevated temperatures and is limited by TJMAX (maximum junction temperature), θJ-A (junction to ambient thermal resistance) and TA (ambient temperature). The maximum power dissipation at any temperature is: PDissMAX = (TJMAX - TA) /θJ-A up to the value listed in the Absolute Maximum Ratings. θJ-A for SOT-23 package is 220°C/W, TJMAX = 125°C. (3) The human body model is a 100 pF capacitor discharged through a 1.5 k Ω resistor into each pin. Operating Ratings Maximum Input Supply Voltage 5.5V Maximum Enable Input Voltage VIN Maximum Load Current 20mA Junction Temperature Range (TJ) −40°C to +125°C 2 Submit Documentation Feedback Copyright © 2006–2013, Texas Instruments Incorporated Product Folder Links: LM4128 LM4128Q |
