LD2982Axx  
LD2982Bxx  
Very low drop and low noise voltage regulator with  
inhibit function, low ESR capacitors compatible  
Features  
■ Very low dropout voltage (120 mV at 50 mA  
and 7 mV at 1 mA load)  
■ Very low quiescent current (375 mA typ. at  
50 mA load and 75 mA at 1 mA)  
■ Output current up to 50 mA  
■ Logic controlled electronic shutdown  
■ Output voltage of 1.8, 2.7, 3.2, 3.3 V  
■ Internal current and thermal limit  
SOT23-5L  
■ Available in 1 % tolerance  
(at 25 °C, A version)  
An external capacitor C  
= 10 nF connected  
BYP  
between bypass pin and GND reduce the noise  
to 30 µVrms.  
■ Supply voltage rejection: 45 dB (typ)  
■ Only 1 µF for stability  
Typical application are in cellular phone,  
palmtop/laptop computer, personal digital  
assistant (PDA), personal stereo, camcorder and  
camera.  
■ Low output noise voltage 30 µVrms  
■ Smallest package SOT23-5L  
■ Temperature range: -40 °C to 125 °C  
Description  
The LD2982A/Bxx is a 50 mA 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 1 µA when INHIBIT  
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.
