Ultra low dropout voltage - 100mV @ 50mA  
Guaranteed 50mA output current  
Low ground pin current at all loads  
<1µA quiescent current in shutdown  
Wide supply voltage range 2.5V to 16V in  
Wide output voltage range  
Excellent line regulation  
Surface mount packaging (5 pin SOT-23)  
Industrial temperature range  
The SC2982 is a 50mA ultra low dropout linear  
regulator with a built in CMOS/TTL logic level enable  
switch, designed specifically for battery powered  
applications where low quiescent current and low  
dropout are critical for battery longevity.  
The SC2982 uses a Semtech proprietary internal  
PNP device for the pass element, providing a low  
dropout voltage of 100mV at a load of 50mA, while  
maintaining a ground pin current of 600µA.  
APPLICATIONS  
The output noise is reduced by placing a 10nF  
capacitor on pin 4 (bypass).

Battery Powered Systems  
Cellular Telephones  
Cordless Telephones  
Pagers, Personal Digital Assistants  
Portable Instrumentation  
Each device contains a bandgap reference, error  
amplifier, PNP pass element, thermal and current  
limiting circuitry and resistor divider network for setting  
output voltage.  
Cameras, Portable Consumer Equipment  
PCMCIA VCC & VPP Regulation/Switching  
The SC2982 is packaged in a 5 pin SOT-23 surface  
mount package for a very small footprint and it  
requires only a 1µF capacitor on the output for a  
minimum number of external components.
