LD6836 series
Ultra low dropout regulators, low noise, 300 mA
Rev. 2 — 5 October 2012
Product data sheet
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 (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.

LD6836TD
[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.

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). Permanent conditions are
a constant output current and a ripple-free input voltage. The output noise voltage is
generated by the LDO regulator.

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.

10. Application information
10.1 Capacitor values
The LD6836 series require external capacitors at the output to guarantee a stable
regulator behavior. Do 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 LD6836 series. Also an input capacitor
is recommended to keep the input voltage stable.

This product has been qualified in accordance with NX1-00023 NXP Semiconductors
Quality and Reliability Specification and is suitable for use in consumer applications.
12. Marking
12.1 WLCSP4
WLCSP dies are laser marked with the following information (see Table 14 to 16 and
Figure 21):
1. Shaded area: marking of pin A1
2. The character N gives the version code and describes the output mode of the LDO. If
the code is legible, the LDO has an integrated pull down transistor (“P“ version). If the
character N is rotated counterclockwise by 90°, the LDO is a “H“ version.
3. “YYY” symbolizes a placeholder for some characters of the lot ID

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.

LD6836 series
NXP Semiconductors
Ultra low dropout regulators, low noise, 300 mA
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 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
