LP8340 Low Dropout, Low IQ, 1.0A CMOS Linear Regulator  
Check for Samples: LP8340

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.

±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.  
LP8340I 40°C to 125°C
