General Description

SLUS234D – JANUARY 2000 – REVISED FEBRUARY 2002 DP PACKAGE (FRONT VIEW) VOUTS 1 8 SD/CT VIN 2 7 VIN VIN 3 6 VIN GND 4 5 VOUT 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.
