The SMS5105 is offered as fixed voltage regulators in the 5 lead SOT-23, SOT-89, SOT-223, and 8 lead SOIC packages, and as adjustable voltage regulators in the 5 lead SOT-23 and 8 lead SOIC packages.

HIGH RELIABILITY BARE DIE AND SYSTEM IN PACKAGE - SHORT APPLICATION NOTE COB (Chip on Board) and SiP (System-in-Package) are integrating proven mature products in bare die of mixed technologies i.e. Si, GaAs, GaN, InP, passive components, etc that cannot be easily implemented in SOC (System-on-Chip) technology. COB and SiP have small size footprint, high density, shorter design cycle time, easier to redesign and rework, use simpler and less expensive assembly process. For extreme applications the bare die has to withstand also harsh environmental conditions without the protection of a package. KGD, Known Good Die concept is no longer satisfactory if the die cannot withstand harsh environmental conditions and degrades. Standard semiconductor devices supplied by many manufacturers in bare die are build with exposed aluminum pads that are extremely sensitive to moisture and corrosive components of the atmosphere. Semiconix has reengineered industry standard products and now offers known good die for bare die applications with gold interconnection and well-engineered materials that further enhance the die reliability. Semiconix also offers Silicon Printed Circuit Board technology with integrated passive components as a complete high reliability SIP solution for medical, military and space applications. See AN-SMX-001 DISCRETE SEMICONDUCTORS MANUFACTURING PROCESS Discrete semiconductors are manufactured using Semiconix in house high reliability semiconductor manufacturing processes.

Temperature Stability of VO: The percentage change in output voltage for a thermal variation from room temperature to either temperature extreme. External capacitor The SMS5105 series require an output capacitor of 2.2µF or greater to ensure device stability. Without the capacitor the device may oscillate. Most type of tantalum or electrolytic capacitor can be used in the applications. A critical characteristic of the capacitors is an ESR value of 5Ω or less and a resonant frequency above 500kHz. The value of this capacitor can be increased without limits. For higher loads, the value of the capacitor should be increased, specially when the output voltage is set for 2.5V or less. The SMS5105 lowest fixed output voltage value is 1.5V. Programming the Output Voltage The SMS5105 may be programmed for any output voltage between its 1.25V reference and its 6V maximum rating, allowing for dropout and power dissipation. As shown, an external pair of resistors is required. The equation for the output voltage is: Vout=Vref(1+R12/R2) where VREF is the nominal 1.25 reference voltage.

For AuSn or AuGe die attach process, Ti/Pt/Au or Ti/Pd/Au are recommended backside metallization. For soft solder die attach, backside metallization may be any of Ti/Ni/Au, Ti/Pt/Au, Ti/Pd/Au. For silver filled conductive epoxy die attach, AuSi as well as Ti/Ni/Au, Ti/Pt/Au, Ti/Pd/Au may be used. In general, after die attach, prior to wire bonding operation an oxygen RF plasma clean operation is recommended. IMPORTANT NOTE: Aluminum wire should not be used with gold pads due to potential reliability problem known as purple plague. Same it applies to Aluminum bonding pads with gold wire! In the transition from SnPb solder to lead free and RoHS compliant packaging and assembly processes the reflow temperature has increased in some cases from 180°C to 220°C. This may cause an increase of the rate of formation of gold aluminum intermetallic compounds that are brittle and are conducive to increased contact resistance and or bond failure.

Semiconix standard bare die components are designed for thermosonic GOLD wire bonding and AuSi eutectic die attach. For AuSn or AuGe die attach process, Ti/Pt/Au or Ti/Pd/Au are recommended backside metallization.
For soft solder die attach, backside metallization may be any of Ti/Ni/Au, Ti/Pt/Au, Ti/Pd/Au.
For silver filled conductive epoxy die attach, AuSi as well as Ti/Ni/Au, Ti/Pt/Au, Ti/Pd/Au may be used.
In general, after die attach, prior to wire bonding operation an oxygen RF plasma clean operation is recommended.
IMPORTANT NOTE: Aluminum wire should not be used with gold pads due to potential reliability problem known as purple plague. Same it applies to Aluminum bonding pads with gold wire! In the transition from SnPb solder to lead free and RoHS compliant packaging and assembly processes the reflow temperature has increased in some cases from 180°C to 220°C. This may cause an increase of the rate of formation of gold aluminum intermetallic compounds that are brittle and are conducive to increased contact resistance and or bond failure. See Application note AN-SMX-000.
