LD6806 series Ultra low-dropout regulator, low noise, 200 mA Rev. 3 — 9 December 2011 Product data sheet 1. Product profile 1.1 General description The LD6806 series is a small-size Low-DropOut regulator (LDO) family with a typical voltage drop of 60 mV at 200 mA current rating. The device is available in three different surface-mounted packages, one 0.4 mm pitch CSP, one leadless plastic package SOT886 and one gull wing package SOT753. The operating voltage ranges from 2.3 V to 5.5 V and the output voltage ranges from 1.2 V to 3.6 V. LD6806x/xxH devices show a high-ohmic state at the output pin, while the LD6806x/xxP contains a pull-down switching transistor, to provide a low-ohmic output stage when the device is disabled. All devices use the same regulator design and are manufactured in monolithic silicon technology. These features make the LD6806 series ideal for use in applications requiring component miniaturization, such as mobile phone handsets, cordless telephones and personal digital devices. 1.2 Features and benefits                 Input voltage range 2.3 V to 5.5 V Output voltage range 1.2 V to 3.6 V Dropout voltage 60 mV at 200 mA output rating Low quiescent current in shutdown mode (typical 1.0 A) 30 V RMS output noise voltage (typical value) at 10 Hz to 100 kHz Turn-on time just 200 s 55 dB Power Supply Rejection Ratio (PSRR) at 1 kHz Temperature watchdog Current limiter LD6806xxxH: high-ohmic (3-state) output state when disabled LD6806xxxP: low-ohmic output state when disabled Integrated ESD protection of 10 kV Human Body Model WLCSP with 0.4 mm pitch and package size of 0.76 mm  0.76 mm  0.47 mm SOT886 leadless package 1.0 mm  1.45 mm  0.5 mm SOT753 plastic surface-mounted device Pb-free, RoHS compliant and free of Halogen and Antimony (dark green compliant) LD6806 series NXP Semiconductors Ultra low-dropout regulator, low noise, 200 mA 1.3 Applications  Analog and digital interfaces requiring lower than standard supply voltage in mobile appliances such as mobile phones, media players and so on. 2.

To minimize the effective Rth(j-a), all pins must have a solid connection to larger Cu layer areas for example to the power and ground layer. In multi-layer PCB applications, the second layer should be used to create a large heat spreader area directly below the LDO. If this layer is either ground or power, it should be connected with several vias to the top layer connecting to the device ground or supply. Avoid the use of solder-stop varnish under the chip. [2] Use the measurement data given for a rough estimation of the Rth(j-a) in your application. The actual Rth(j-a) value can vary in applications using different layer stacks and layouts. 8.

Dynamic behavior All results described in Section 9 are based on measurements of types LD6806CX4xxx and LD6806Fxxx from the LD6806 product series within Section 6 “Recommended operating conditions”. 9.1 Dropout The dropout voltage is defined as the smallest input to output voltage difference at a specified load current when the regulator operates within its linear region with the pass transistor functioning as a plain resistor. This means that the input voltage is below the nominal output voltage value. A small dropout voltage guaranties lower power consumption and efficiency maximization.

Application information 10.1 Output capacitor values The LD6806 series requires external capacitors at the output to guarantee a stable regulator behavior. Also an input capacitor is recommended to keep the input voltage stable. These capacitors should not under-run the specified minimum Equivalent Series Resistance (ESR). The absolute value of the total capacitance attached to the output pin OUT influences the shutdown time (tsd(reg)) of the LD6806 series. Table 11. External load capacitor Symbol Parameter Conditions [1] CL(ext) external load capacitance ESR equivalent series resistance [1] Min Typ Max Unit - 1.0 - F 5 - 500 m The minimum value of capacitance for stability and correct operation is 0.7 F. The capacitor tolerance should be 30 % or better over the temperature range. The full range of operating conditions for the capacitor in the application should be considered during device selection to ensure that this minimum capacitance specification is met. The recommended capacitor type is X7R to meet the full device temperature specification of 40 C to +125 C. IN IN OUT EN GND 1μF OUT 1μF 001aan647 Fig 34. Application diagram 11.

A more in-depth account of soldering WLCSP (Wafer Level Chip-Size Packages) can be found in application note AN10439 “Wafer Level Chip Scale Package” and in application note AN10365 “Surface mount reflow soldering description”. Wave soldering is not suitable for this package. LD6806_SER Product data sheet All information provided in this document is subject to legal disclaimers. Rev. 3 — 9 December 2011 © NXP B.V. 2011. All rights reserved. 24 of 36 LD6806 series NXP Semiconductors Ultra low-dropout regulator, low noise, 200 mA All NXP WLCSP packages are lead-free. 14.2 Board mounting Board mounting of a WLCSP requires several steps: 1. Solder paste printing on the PCB 2. Component placement with a pick and place machine 3. The reflow soldering itself 14.3 Reflow soldering Key characteristics in reflow soldering are: • Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to higher minimum peak temperatures (see Figure 43) than a PbSn process, thus reducing the process window • Solder paste printing issues, such as smearing, release, and adjusting the process window for a mix of large and small components on one board • Reflow temperature profile; this profile includes 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) while being 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 Table 15. Table 15. Lead-free process (from J-STD-020C) Package thickness (mm) Package reflow temperature (C) Volume (mm3) < 350 350 to 2000 > 2000 < 1.6 260 260 260 1.6 to 2.5 260 250 245 > 2.5 250 245 245 Moisture sensitivity precautions, as indicated on the packing, must be respected at all times. Studies have shown that small packages reach higher temperatures during reflow soldering, see Figure 43.

Temperature profiles for large and small components For further information on temperature profiles, refer to application note AN10365 “Surface mount reflow soldering description”. 14.3.1 Stand off The stand off between the substrate and the chip is determined by: • The amount of printed solder on the substrate • The size of the solder land on the substrate • The bump height on the chip The higher the stand off, the better the stresses are released due to TEC (Thermal Expansion Coefficient) differences between substrate and chip. 14.3.2 Quality of solder joint A flip-chip joint is considered to be a good joint when the entire solder land has been wetted by the solder from the bump. The surface of the joint should be smooth and the shape symmetrical. The soldered joints on a chip should be uniform. Voids in the bumps after reflow can occur during the reflow process in bumps with high ratio of bump diameter to bump height, i.e. low bumps with large diameter. No failures have been found to be related to these voids. Solder joint inspection after reflow can be done with X-ray to monitor defects such as bridging, open circuits and voids. 14.3.3 Rework In general, rework is not recommended. By rework we mean the process of removing the chip from the substrate and replacing it with a new chip. If a chip is removed from the substrate, most solder balls of the chip will be damaged. In that case it is recommended not to re-use the chip again. LD6806_SER Product data sheet All information provided in this document is subject to legal disclaimers.

All rights reserved. 26 of 36 LD6806 series NXP Semiconductors Ultra low-dropout regulator, low noise, 200 mA Device removal can be done when the substrate is heated until it is certain that all solder joints are molten. The chip can then be carefully removed from the substrate without damaging the tracks and solder lands on the substrate. Removing the device must be done using plastic tweezers, because metal tweezers can damage the silicon. The surface of the substrate should be carefully cleaned and all solder and flux residues and/or underfill removed. When a new chip is placed on the substrate, use the flux process instead of solder on the solder lands. Apply flux on the bumps at the chip side as well as on the solder pads on the substrate. Place and align the new chip while viewing with a microscope. To reflow the solder, use the solder profile shown in application note AN10365 “Surface mount reflow soldering description”. 14.3.4 Cleaning Cleaning can be done after reflow soldering. 15. Soldering of SMD packages This text provides a very brief insight into a complex technology. A more in-depth account of soldering ICs can be found in Application Note AN10365 “Surface mount reflow soldering description”. 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 electrical circuits. The soldered joint provides both the mechanical and the electrical connection. There is no single soldering 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 probability 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. Key characteristics in both wave and reflow soldering are: • Board specifications, including the board finish, solder masks and vias • Package footprints, including solder thieves and orientation LD6806_SER Product data sheet All information provided in this document is subject to legal disclaimers.

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 Table 16 and 17 Table 16.

Mounting 16.1 PCB design guidelines It is recommended, for optimum performance, to use a Non-Solder Mask Defined (NSMD), also known as a copper-defined design, incorporating laser-drilled micro-vias connecting the ground pads to a buried ground-plane layer. This results in the lowest possible ground inductance and provides the best high frequency and ESD performance. Refer to Table 18 for the recommended PCB design parameters. Table 18.
