FEATURES  
DESCRIPTION  
The LP38690/2 low dropout CMOS linear regulators  
2
•
•
2.5% Output Accuracy (25°C)  
provide tight output tolerance (2.5% typical),  
extremely low dropout voltage (450mV @ 1A load  
current, VOUT = 5V), and excellent AC performance  
utilizing ultra low ESR ceramic output capacitors.  
Low Dropout Voltage: 450mV @ 1A (typ, 5V  
out)  
•
•
•
•
•
•
•
•
Wide Input Voltage Range (2.7V to 10V)  
Precision (Trimmed) Bandgap Reference  
Ensured Specs for -40°C to +125°C  
1µA Off-State Quiescent Current  
Thermal Overload Protection  
The low thermal resistance of the WSON, SOT-223  
and PFM packages allow the full operating current to  
be used even in high ambient temperature  
environments.  
The use of a PMOS power transistor means that no  
DC base drive current is required to bias it allowing  
ground pin current to remain below 100 µA  
regardless of load current, input voltage, or operating  
temperature.  
Foldback Current Limiting  
PFM, SOT-223 and 6-Lead WSON Packages  
Enable Pin (LP38692)  
APPLICATIONS  
Dropout Voltage: 450 mV (typ) @ 1A (typ. 5V out).  
Ground Pin Current: 55 µA (typ) at full load.  
Precision Output Voltage: 2.5% (25°C) accuracy.
