Low dropout regulators, high PSRR, 150 mA
Rev. 2 — 14 December 2012
Product data sheet
1. Product profile
1.1 General description
Small-size Low DropOut regulator (LDO) family with ultra high Power Supply Rejection
Ratio (PSRR) of 75 dB. The typical 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
nominal output voltages VO(nom) between 1.2 V and 3.6 V.
The LD6815TD/xxH devices show a high-ohmic state (3-state) at the output pin when set
to disabled mode. The LD6815TD/xxP devices contain a pull-down switching transistor to
provide a low-ohmic output state (auto discharge function) in disabled mode.
The LD6815 series devices are available in SOT753 (TSOP5) plastic package with a size
of 2.9 1.5 1.0 mm. All devices are manufactured in monolithic silicon technology.

[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 multilayer
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. Dynamic behavior
9.1 Dropout voltage
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 Capacitor values
The LD6815 series requires 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 LD6815 series. Also an input capacitor
is recommended to keep the input voltage stable.

Suitability for use — NXP Semiconductors products are not designed,
authorized or warranted to be suitable for use in life support, life-critical or
safety-critical systems or equipment, nor in applications where failure or
malfunction of an NXP Semiconductors product can reasonably be expected
to result in personal injury, death or severe property or environmental
damage. NXP Semiconductors and its suppliers accept no liability for
inclusion and/or use of NXP Semiconductors products in such equipment or
applications and therefore such inclusion and/or use is at the customer’s own
risk.
Applications — Applications that are described herein for any of these
products are for illustrative purposes only. NXP Semiconductors makes no
representation or warranty that such applications will be suitable for the
specified use without further testing or modification.
Customers are responsible for the design and operation of their applications
and products using NXP Semiconductors products, and NXP Semiconductors
accepts no liability for any assistance with applications or customer product
design. It is customer’s sole responsibility to determine whether the NXP
Semiconductors product is suitable and fit for the customer’s applications and
products planned, as well as for the planned application and use of
customer’s third party customer(s). Customers should provide appropriate
design and operating safeguards to minimize the risks associated with their
applications and products.
NXP Semiconductors does not accept any liability related to any default,
damage, costs or problem which is based on any weakness or default in the
customer’s applications or products, or the application or use by customer’s
third party customer(s). Customer is responsible for doing all necessary
testing for the customer’s applications and products using NXP
Semiconductors products in order to avoid a default of the applications and
the products or of the application or use by customer’s third party
customer(s). NXP does not accept any liability in this respect.
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
