| 1. product profile 1.1 general description the LD6836 series is a small-size low dropout regulator (ldo) family with a typical voltage drop of 90 mv at 300 ma current rating. operating input voltages can range from 2.3 v to 5.5 v. the devices are available with fixed output voltages between 1.2 v and 3.6 v. in disabled mode the LD6836x/xxh devices show a high-ohmic state at the output pin while the LD6836x/xxp devices contain a pull- down switching transistor to provide a low-ohmic output state (a uto discharge function). the LD6836cx4 and LD6836cx4/c devices are in a 0.4 mm pitch wafer-level chip-scale package (wlcsp) making them ideal for use in portable applications requiring component miniaturization. the LD6836td devices are in a small sot753 surface-mounted device (smd) plastic pack age. all devices are manufactured in monolithic silicon technology. 1.2 features and benefits ? 300 ma output current rating ? input voltage range 2.3 v to 5.5 v ? fixed output voltage between 1.2 v and 3.6 v ? dropout voltage 90 mv at 300 ma output rating ? low quiescent current in shutdown mode (typical 0.1 ? a) ? 30 ? v rms output noise voltage (typical value) at 10 hz to 100 khz ? turn-on time 150 ? s ? 55 db power supply rejection ratio (psrr) at 1 khz ? over-temperature protection ? output current limiter ?

. 15.1 introduction to soldering soldering is one of the most common methods through which packages are attached to printed circuit boards (pcbs), to form electr ical circuits. the soldered joint provides both the mechanical and the electrical connection. th ere is no single sold ering method that is ideal for all ic packages. wave soldering is often preferred when through-hole and surface mount devices (smds) are mixed on one printed wiring board; however, it is not suitable for fine pitch smds. reflow soldering is ideal for the small pitches and high densities that come with increased miniaturization. 15.2 wave and reflow soldering wave soldering is a joining technology in which the joints are made by solder coming from a standing wave of liquid solder. the wave soldering process is suitable for the following: ? through-hole components ? leaded or leadless smds, which are glued to the surface of the printed circuit board not all smds can be wave soldered. packages with solder balls, and some leadless packages which have solder lands underneath the body, cannot be wave soldered. also, leaded smds with leads having a pitch smaller than ~0.6 mm cannot be wave soldered, due to an increased pr obability of bridging. the reflow soldering process involves applying solder paste to a board, followed by component placement and exposure to a temperature profile. leaded packages, packages with solder balls, and leadless packages are all reflow solderable. fig 27. reflow soldering footprint sot753 solder lands solder resist occupied area solder paste sot753_fr 2.8253.3 0.45 (5) 0.55 (5) 0.7 (5) 0.8 (5) 3.45 1.95 0.95 0.95 2.4 dimensions in mm free datasheet http://www.datasheet.in/ LD6836_ser all information provided in this document is subject to legal disclaimers. ?

board specifications, in cluding the board finish , solder masks and vias ? package footprints, including solder thieves and orientation ? the moisture sensitivit y level of the packages ? package placement ? inspection and repair ? lead-free soldering versus snpb soldering 15.3 wave soldering key characteristics in wave soldering are: ? process issues, such as application of adhe sive and flux, clinching of leads, board transport, the solder wave parameters, and the time during which components are exposed to the wave ? solder bath specifications, including temperature and impurities 15.4 reflow soldering key characteristics in reflow soldering are: ? lead-free versus snpb solderi ng; note that a lead-free reflow process usually leads to higher minimum peak temperatures (see figure 28 ) than a snpb process, thus reducing the process window ? solder paste printing issues including smearing, release, and adjusting the process window for a mix of large and small components on one board ? reflow temperature profile; this profile includ es preheat, reflow (in which the board is heated to the peak temperature) and cooling down. it is imperative that the peak temperature is high enough for the solder to make reliable solder joints (a solder paste characteristic). in addition, the peak temperature must be low enough that the packages and/or boards are not damaged. the peak temperature of the package depends on package thickness and volume and is classified in accordance with ta b l e 2 2 and 23 table 22. snpb eutectic process (from j-std-020c) package thickness (mm) package reflow temperature ( ?c) volume (mm 3 ) < 350 ?
