description  
The UCC384-x family of negative linear-series pass regulators is tailored for low-dropout applications where  
low-quiescent power is important. Fabricated with a BCDMOS technology ideally suited for low input-to-output  
differential applications, the UCC384-x passes 0.5 A while requiring only 0.2 V of input-voltage headroom.  
Dropout voltage decreases linearly with output current, so that dropout at 50 mA is less than 20 mV.  
Quiescent current consumption for the device under normal (non-dropout) conditions is typically 200 µA. An  
integrated charge pump is internally enabled only when the device is operating near dropout with low VIN. This  
ensured that the device meets the dropout specifications even for maximum load current and a VIN of –3.2 V  
with only a modest increase in quiescent current. Quiescent current is always less than 350 µA, with the charge  
pump enabled. The quiescent current of the UCC384 does not increase with load current.  
Short-circuit current is internally limited. The device responds to a sustained overcurrent condition by turning  
off after a t  
beginspulsingonandoffatthet /t  
delay. The device then stays off for a period, t  
, that is 40 times the t  
delay. The device then

short circuit such that heat sinking, if at all required, must only accommodate normal operation. An external  
capacitor sets the on time. The off time is always 40 times t  
.

The UCCx84-x can be shutdown to 45 µA (maximum) by pulling the SD/CT pin more positive than –0.7 V. To  
allow for simpler interfacing, the SD/CT pin may be pulled up to 6 V above the ground pin without turning on  
clamping diodes.  
Internal power dissipation is further controlled with thermal-overload protection circuitry. Thermal shutdown  
occurs if the junction temperature exceeds 140°C. The chip remains off until the temperature has dropped 20°C  
(T = 120°C).
