Rev. 2 — 25 June 2012  
Product data sheet  
1. Product profile  
1.1 General description  
The LD6805 series is a small-size Low DropOut regulator (LDO) family with ultra high  
Power Supply Rejection Ratio (PSRR) of 75 dB. The voltage drop is 250 mV at 150 mA  
current rating.  
Operating voltages can range from 2.3 V to 5.5 V. The devices are available with fixed  
output voltages between 1.2 V to 3.6 V.  
The LD6805K/xxH devices show a high-ohmic state at the output pin when set to disabled  
mode. The LD6805K/xxP devices contain a pull-down switching transistor to provide a  
low-ohmic output state (auto discharge function) in disabled mode.  
The LD6805 series devices are available in a 1 1 mm DFN plastic package making them  
ideal for use in portable applications requiring component miniaturization. All devices are  
manufactured in monolithic silicon technology.

[1] The (absolute) maximum power dissipation depends on the junction temperature Tj. Higher power dissipation is allowed with lower  
ambient temperatures. The conditions to determine the specified values are Tamb = 25 C and the use of a two layer PCB.

[1] The overall Rth(j-a) can vary depending on the board layout. 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 is used to create a  
large heat spreader area directly below the LDO. If this layer is either ground or power, it is 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.

9.2 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. This means that  
the input voltage is below the nominal output voltage value and the pass transistor works  
as a plain resistor.  
A small dropout voltage guarantees lower power consumption and efficiency  
maximization.

10. Application information  
10.1 Output capacitor values  
The LD6805 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. It is not allowed to 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 LD6805 series.

[1] The minimum value of capacitance for stability and correct operation is 0.7 F. The specified capacitor  
tolerance is 30 % or better over the temperature and operating conditions range. The recommended  
capacitor type is X7R to meet the full device temperature specification of 40 C to +125 C.

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  
The moisture sensitivity 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 adhesive 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 soldering; note that a lead-free reflow process usually leads to  
higher minimum peak temperatures (see Figure 10) 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 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). 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 12 and 13

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 10.
