LP8340 Low Dropout, Low IQ, 1.0A CMOS Linear Regulator  
Check for Samples: LP8340  
1
FEATURES  
DESCRIPTION  
The LP8340 low-dropout CMOS linear regulator is  
available in 5V, 3.3V, 2.5V, 1.8V and adjustable  
output versions. Packaged in the 6ld WSON package  
and 3ld PFM. The LP8340 can deliver up to 1.0A  
output current.  
2
±1.5% Typical VOUT Tolerance  
420mV Typical Dropout @ 1.0A (VO = 5V)  
Wide Operating Range 2.7V to 10V  
Internal 1.0A PMOS Output Transistor  
19µA Typical Quiescent Current  
Thermal Overload Limiting  
Typical dropout voltage is 420mV at 1.0A for the 5.0V  
version, 540mV at 1.0A for the 3.3V version, 670mV  
at 1.0A for the 2.5V version and 680mV at 800mA for  
the 1.8V version.  
Foldback Current Limiting  
Zener Trimmed Bandgap Reference  
Space Saving WSON package  
Temperature Range  
The LP8340 includes a zener trimmed bandgap  
voltage reference, foldback current limiting and  
thermal overload limiting.  
LP8340C 0°C to 125°C  
The LP8340 features a PMOS output transistor which  
unlike PNP type low dropout regulators requires no  
base drive current. This allows the device ground  
current to remain less than 50µA over operating  
temperature, supply voltage and irrespective of the  
load current.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam  
during storage or handling to prevent electrostatic damage to the MOS gates.

(4) Maximum Power dissipation for the device is calculated using the following equations:  
where TJ(MAX) is the maximum  
junction temperature, TA is the ambient temperature, and θJA is the junction-to-ambient thermal resistance. The value of the θJA for the  
WSON package is specifically dependant on the PCB trace area, trace material, and the number of layers and thermal vias. For  
improved thermal resistance and power dissipation for the WSON package, refer to Application Note AN-1187 (SNOA401).

APPLICATIONS SECTION  
GENERAL INFORMATION  
The LP8340 is a low-dropout, low quiescent current linear regulator. As shown in Figure 22 it consists of a 1.25V  
reference, error amplifier, MOSFET driver, PMOS pass transistor and for the fixed output versions, an internal  
feedback network (R1/R2). In addition, the device is protected from overload by a thermal shutdown circuit and a  
foldback current limit circuit  
The 1.25V reference is connected to the inverting input of the error amplifier. Regulation of the output voltage is  
achieved by means of negative feedback to the non-inverting input of the error amplifier. Feedback resistors R1  
and R2 are either internal or external to the device, depending on whether it is a fixed voltage version or the  
adjustable version. The negative feedback and high open loop gain of the error amplifier cause the two inputs of  
the error amp to be virtually equal in voltage. If the output voltage changes due to load changes, the error  
amplifier and MOSFET driver provide the appropriate drive to the pass transistor to maintain the error amplifier’s  
inputs as virtually equal.

EXTERNAL CAPACITOR  
An Input capacitor of 1μF or greater is required between the LP8340 VIN pin and ground. While 1μF will provide  
adequate bypassing of the VIN supply larger values of input capacitor (i.e. 10μF) can provide improved bypassing  
of power supply noise.  
Stable operation can be achieved with an output capacitor of 1μF or greater, either ceramic X7R dielectric or  
aluminum/tantalum electrolytic. While the minimum capacitor value is 1μF, the typical output capacitor values  
selected range from 1μF to 10μF. The larger values provide improved load-transient response, power supply  
rejection and stability.

OUTPUT VOLTAGE SETTING (ADJ VERSION ONLY)  
The output voltage is set according to the amount of negative feedback (Note that the pass transistor inverts the  
feedback signal). This feedback is determined by R1 and R2 with the resulting output voltage represented by the  
following equation:

Use the following equation to determine the values of R1 and R2 for a desired VOUT (R2 = 100kΩ is  
recommended).

MINIMUM LOAD CURRENT  
A minimum load of 100μA is required for regulation and stability over the entire operating temperature range. If  
actual load current fall below 100μA it is recommended that a resistor of value RL = VO/100μA be placed  
between VO and ground.  
START UP CONSIDERATIONS  
Under certain operating conditions, overshoot of VOUT at start-up can occur. The observed overshoot is a  
function of rise time of VIN waveform, COUT, start-up load current, and VINVOUT differential. The relationship  
between these conditions is shown in the Typical Performance Characteristics curves (Minimum Input Voltage  
Rise Time). VIN rise times above the curve result in <5% overshoot.  
Customers are encouraged to check the suitability of LP8340 in their specific application.

(1) The marketing status values are defined as follows:  
ACTIVE: Product device recommended for new designs.  
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.  
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.  
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.  
OBSOLETE: TI has discontinued the production of the device.  
(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability  
information and additional product content details.  
TBD: The Pb-Free/Green conversion plan has not been defined.  
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that  
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.  
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between  
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.  
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight  
in homogeneous material)  
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.  
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.  
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation  
of the previous line and the two combined represent the entire Device Marking for that device.  
(6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish  
value exceeds the maximum column width.
