LD2981  
Ultra low-drop voltage regulators with inhibit  
Datasheet - production data  
Description  
The LD2981 is a 100 mA fixed-output voltage  
regulator. The low-drop voltage and the 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  
1 μA 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.  
Features  
Ultra low dropout voltage (0.17 V typ. at 100  
mA load, 7 mV typ. at 1 mA load)  
Very low quiescent current (80 μA typ. at no  
load in on mode; max 1 μA in off mode)  
Guaranteed output current up to 100 mA  
Logic-controlled electronic shutdown  
Output voltage of 2.5; 3.0; 3.3; 5.0 V  
Internal current and thermal limit  
± 0.75% tolerance output voltage available  
(A version)  
Output low noise voltage 160 μVRMS  
Temperature range: -40 to 125 °C  
Small package SOT23-5L and SOT-89  
Fast dynamic response to line and load
