pin is pulled low. Shutdown Logic Control Function  
is available on pin 3 (TTL compatible). This means  
that when the device is used as local regulator, it  
is possible to put a part of the board in standby,  
decreasing the total power consumption.  
DESCRIPTION  
An external capacitor  
C
=10nF connected  
BYP  
The LD2982 is a 50mA fixed output voltage  
regulator. The ultra low drop voltage and the low  
quiescent current make them particularly suitable  
for low noise, low power applications, and in  
battery powered systems. In sleep mode  
quiescent current is less than 1µA when INHIBIT  
between bypass pin and GND reduce the noise  
to 30µVrms.  
Typical application are in cellular phone, palmtop/  
laptop computer, personal digital assistant (PDA),  
personal stereo, camcorder and camera.
