ultra low quiescent current make them suitable for  
low noise, low power applications and in battery  
powered systems.  
The quiescent current in sleep mode is less than  
1µA when INHIBIT pin is pulled low. Shutdown  
Logic Control function is available on pin n.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. The LD2981 is designed to  
work with low ESR ceramic capacitor. Typical  
applications are in cellular phone, palmtop/laptop  
computer, personal digital assistant (PDA),  
personal stereo, camcorder and camera.
