Description
The TS31x23 high voltage linear regulator consists of a low power amplifier with a high voltage p-channel pass gate. The linear regulator has a wide operating range, and is ideal for systems that may have large voltage transients and require the output load to remain regulated. An analog current limit is used to limit output current and protect the regulator from external short circuits. Summary Specification
- Ambient operating temperature 0C to 85C
- Packaged in a 8pin DFN (2x2) Typical Application Circuit

Final Datasheet Rev 1.1 March 19, 2015 www.semtech.com 8 of 15 Semtech Proprietary & Confidential Application Using A Multi-Layer PCB Multi-Layer Board (Cross-sectional View) JEDEC standard FR4 PCB Cross-section: In a multi-layer board application, the thermal vias are the primary method of heat transfer from the package thermal pad to the internal ground plane. The efficiency of this method depends on several factors, including die area, number of thermal vias, thickness of copper, etc. To maximize the efficiency of this package for application on a single layer or multi-layer PCB, certain guidelines must be followed when laying out this part on the PCB. The following are guidelines for mounting the exposed pad IC on a Multi-Layer PCB with ground a plane.
Final Datasheet Rev 1.1 March 19, 2015 www.semtech.com 9 of 15 Semtech Proprietary & Confidential Application Using A Single Layer PCB The above drawing is a representation of how the heat can be conducted away from the die using an exposed pad package. Each application will have different requirements and limitations and therefore the user should use sufficient copper to dissipate the power in the system. The output current rating for the linear regulators may have to be de-rated for ambient temperatures above 85C. The de-rate value will depend on calculated worst case power dissipation and the thermal management implementation in the application. Layout recommendations for a Single Layer PCB: utilize as much Copper Area for Power Management. In a single layer board application the thermal pad is attached to a heat spreader (copper areas) by using low thermal impedance attachment method (solder paste or thermal conductive epoxy). In both of the methods mentioned above it is advisable to use as much copper traces as possible to dissipate the heat. Important: If the attachment method is NOT implemented correctly, the functionality of the product is not guaranteed. Power dissipation capability will be adversely affected if the device is incorrectly mounted onto the circuit board. Note: NOT to Scale

Note 2: The maximum component temperature reached during reflow depends on package thickness and volume. The use of convection reflow processes reduc- es the thermal gradients between packages. However, thermal gradients due to differences in thermal mas of SMD packages may still exist. Note 3: Components intended for use in a “lead-free” assembly process shall be evaluated using the “lead-free” peak temperature and profiles defined in Tables 4-1, 4.2 and 5-2 whether or not lead free.
