±1.5% Typical VOUT Tolerance  
210mV Typical Dropout @ 500mA (VO = 5V)  
Wide Operating Range 2.7V to 10V  
Internal 500mA PMOS Output Transistor  
19µA Typical Quiescent Current  
Thermal Overload Limiting  
available in 5V, 3.3V, 2.5V, 1.8V or adjustable output  
versions. Packaged in our 6ld WSON package and  
3ld DPAK they can deliver up to 500mA output  
current.  
Typical dropout voltage @ 500mA is 210mV for the  
5.0V version, 270mV for the 3.3V version and 335mV  
for the 2.5V version.  
Foldback Current Limiting  
The devices include a zener trimmed bandgap  
voltage reference, foldback current limiting and  
thermal overload limiting.  
Zener Trimmed Bandgap Reference  
Space Saving WSON package  
Temperature Range  
The LP8345 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.
