LM3490 www.ti.com SNVS012E – JUNE 1999 – REVISED APRIL 2013 LM3490 100 mA, SOT-23, Quasi Low-Dropout Linear Voltage Regulator with LogicControlled ON/OFF Check for Samples: LM3490 FEATURES DESCRIPTION • • • The LM3490 is an integrated linear voltage regulator. It features operation from an input as high as 30V and a specified maximum dropout of 1.2V at the full 100 mA load. Standard packaging for the LM3490 is the 5-lead SOT-23 package. A logic-controlled ON/OFF feature makes the LM3490 ideal for powering subsystems ON and OFF as needed. 1 2 3.3, 5, 12, and 15V Versions Available Logic-Controlled ON/OFF Packaged in the Tiny 5-Lead SOT-23 Package APPLICATIONS • • • • Tiny Alternative to LM78LXX Series and Similar Devices Tiny 5V±5% to 3.3V, 100 mA Converter Post Regulator for Switching DC/DC Converter Bias Supply for Analog Circuits KEY SPECIFICATIONS • • • • • 30V Maximum Input for Operation 1.2V Specified Maximum Dropout over Full Load and Temperature Ranges 100 mA Specified Load Current ±5% Specified Output Voltage Tolerance over Full Load and Temperature Ranges −40 to +125°C Junction Temperature Range for Operation Typical Application Circuit The 5, 12, and 15V members of the LM3490 series are intended as tiny alternatives to industry standard LM78LXX series and similar devices. The 1.2V quasi low dropout of LM3490 series devices makes them a nice fit in many applications where the 2 to 2.5V dropout of LM78LXX series devices precludes their (LM78LXX series devices) use. The LM3490 series features a 3.3V member. The SOT packaging and quasi low dropout features of the LM3490 series converge in this device to provide a very nice, very tiny 3.3V, 100 mA bias supply that regulates directly off the system 5V±5% power supply.

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.

Operating Ratings are conditions under which operation of the device is specified. Operating Ratings do not imply ensured performance limits. For ensured performance limits and associated test conditions, see the Electrical Characteristics tables. If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and specifications. The Absolute Maximum power dissipation depends on the ambient temperature and can be calculated using P = (TJ - TA)/θJA where TJ is the junction temperature, TA is the ambient temperature, and θJA is the junction-to-ambient thermal resistance. The 400 mW rating results from substituting the Absolute Maximum junction temperature, 150°C, for TJ , 50°C for TA, and 250°C/W for θJA. More power can be safely dissipated at lower ambient temperatures. Less power can be safely dissipated at higher ambient temperatures. The Absolute Maximum power dissipation can be increased by 4 mW for each °C below 50°C ambient. It must be derated by 4 mW for each °C above 50°C ambient. A θJA of 250°C/W represents the worst-case condition of no heat sinking of the 5-lead plastic SOT-23 package. Heat sinking enables the safe dissipation of more power. The LM3490 actively limits its junction temperature to about 150°C. Times shown are dwell times. Temperatures shown are dwell temperatures. For detailed information on soldering plastic small-outline packages, see http://www.ti.com. For testing purposes, ESD was applied using the human-body model, a 100 pF capacitor discharged through a 1.5 kΩ resistor.

Operating Ratings are conditions under which operation of the device is specified. Operating Ratings do not imply ensured performance limits. For ensured performance limits and associated test conditions, see the Electrical Characteristics tables. As with the Absolute Maximum power dissipation, the maximum power dissipation for operation depends on the ambient temperature. The 300 mW rating appearing under Operating Ratings results from substituting the maximum junction temperature for operation, 125°C, for TJ, 50°C for TA, and 250°C/W for θJA in P = (TJ − TA)/θJA. More power can be dissipated at lower ambient temperatures. Less power can be dissipated at higher ambient temperatures. The maximum power dissipation for operation appearing under Operating Ratings can be increased by 4 mW for each °C below 50°C ambient. It must be derated by 4 mW for each °C above 50°C ambient. A θJA of 250°C/W represents the worst-case condition of no heat sinking of the 5-lead plastic SOT-23 package. Heat sinking enables the dissipation of more power during operation.

The defined operating voltage range for this pin is 0.0V to 5.0V. The ON/OFF pin can not be left floating, as the output status cannot be ensured. Additionally, the ON/OFF pin should not be biased below ground potential as unpredictable device behavior may occur. Pulling the ON/OFF pin voltage to a value between the VIH threshold and 5.0V will enable the output voltage. Pulling the ON/OFF pin voltage to a value between the VIL threshold and Ground potential will disable the output voltage. Although the ON/OFF threshold is typically 725mV, and has no hysteresis, the ON/OFF signal must rise and fall, cleanly and promptly, from voltage levels that are below the VIL threshold and above the VIH threshold. The ON/OFF pin has no internal pull-up or pull-down to establish a default condition and, as a result, this pin must be terminated, either actively or passively, to an appropriate voltage level.

Unless TI has explicitly designated an individual product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949 and ISO 26262), TI is not responsible for any failure to meet such industry standard requirements. Where TI specifically promotes products as facilitating functional safety or as compliant with industry functional safety standards, such products are intended to help enable customers to design and create their own applications that meet applicable functional safety standards and requirements. Using products in an application does not by itself establish any safety features in the application. Designers must ensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products in life-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use. Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., life support, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, all medical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S. TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product). Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applications and that proper product selection is at Designers’ own risk. Designers are solely responsible for compliance with all legal and regulatory requirements in connection with such selection.
