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 (auto 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 package. All devices are manufactured in monolithic silicon technology.

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.
9.3 Accuracy
The LD6836 series guarantees high accuracy of the nominal output voltage. Fig 8. Dropout voltage as a function of output current for LD6836CX4/25x Fig 9.

9.4 Quiescent current
Quiescent (or ground) current is the difference between input and output current of the regulator.
9.5 Noise
Output noise voltage of an LDO circuit is given as noise density or RMS output noise voltage over a defined frequency spectrum (10 Hz to 100 kHz).

9.8 Start-up and shutdown
Start-up time defines the time needed for the LDO to achieve 95 % of its typical output voltage level after activation via the enable pin. Shutdown time defines the time needed for the LDO to pull-down the output voltage to 10 % of its nominal output voltage after deactivation via the enable pin.
9.9 Enable threshold voltage
An active HIGH signal enables the LDO when the signal exceeds the minimum input HIGH voltage threshold. The LDO is in Off state as long the signal is below the maximum LOW threshold. The input voltage threshold is independent from the LDO input voltage. Fig 17. Start-up for LD6836x/33P Fig 18.

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. Fig 27.

- Package footprints, including solder thieves and orientation
- The moisture sensitivity level of the packages
- Package placement

15.3 Wave soldering
- 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
- Lead-free versus SnPb soldering; 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 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 22 and 23
