description  
The UCC386/7/8 positive linear pass regulator series is tailored for low-dropout applications where extremely  
low quiescent power is required. Fabricated with BiCMOS technology ideally suited for low input to output  
differential applications, the UCC386/7/8 will pass 200 mA while requiring only 200 mV of input voltage  
headroom. Quiescent current is typically less than 10 µA. To prevent reverse current conduction, on-chip  
circuitry limits the minimum forward voltage to 50 mV typical. Once the forward voltage limit is reached, the  
input-output differential voltage is maintained as the input voltage drops until undervoltage lockout disables the  
regulator.
