SC2982  
50mA Ultra Low Dropout, Low  
Noise Micropower Linear Regulator  
PRELIMINARY  
POWER MANAGEMENT  
Description  
Features  
The SC2982 is a 50mA ultra low dropout linear  
regulator with a built in CMOS/TTL logic level enable  
switch. It is designed specifically for battery powered  
applications where low quiescent current and low  
dropout are critical for battery longevity.  
u Ultra low dropout voltage - 100mV @ 50mA  
u Guaranteed 50mA output current  
u Low ground pin current at all loads  
u <1µA quiescent current in shutdown  
u Wide input supply voltage range 2.5V to 16V  
u Wide output voltage range  
u Excellent line regulation  
u Industrial temperature range  
u Surface mount packaging (5 pin SOT-23)  
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).  
u Battery Powered Systems  
u Cellular Telephones  
u Cordless Telephones  
u Pagers  
u Personal Digital Assistants  
u Portable Instrumentation  
u Cameras  
Each device contains a bandgap reference, error  
amplifier, PNP pass element, thermal and current  
limiting circuitry and resistor divider network for setting  
output voltage.  
The SC2982 is packaged in a 5 pin SOT-23 surface mount  
package for a very small footprint and requires only a  
1µF capacitor on the output for a minimum number of  
external components.  
u Portable Consumer Equipment  
u PCMCIA Cards

Notes:  
(1) CIN is needed if the device is far from the supply’s filter capacitors, or for operation from a battery. A value of 1µF  
or greater should be used. CIN may be a tantalum or aluminum electrolytic capacitor.  
(2) CO should be a 1µF or greater tantalum or aluminum electrolytic capacitor. Larger value capacitors will improve  
the overall transient response. Due to their very low ESR, ceramic capacitors should not be used.  
(3) CBYP should be placed as close as possible to pin 4 and ground. A 10nF ceramic capacitor is recommended.  
(4) EN should be tied to VIN if the shutdown feature is not required. Maximum EN voltage = VIN.
