LD2982 Détails du produit

DESCRIPTION
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 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.
An external capacitor CBYP=10nF connected 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.

■ VERY LOW DROPOUT VOLTAGE (120mV AT 50mA AND 7mV AT 1mA LOAD)
■ VERY LOW QUIESCENT CURRENT (375µA TYP. AT 50mA LOAD AND 75µA AT 1mA)
■ OUTPUT CURRENT UP TO 50mA
■ LOGIC CONTROLLED ELECTRONIC SHUTDOWN
■ OUTPUT VOLTAGE OF 1.5,1.8, 2.5, 2.8, 2.85,
   3, 3.1, 3.2, 3.3, 3.5, 3.6, 3.8, 4, 4.7, 5V
■ INTERNAL CURRENT AND THERMAL LIMIT
■ AVAILABLE IN ± 1% TOLLERANCE (AT 25°C, A VERSION)
■ SUPPLY VOLTAGE REJECTION: 45dB (TYP)
■ ONLY 1µF FOR STABILITY
■ LOW OUTPUT NOISE VOLTAGE 30µVrms
■ SMALLEST PACKAGE SOT23-5L
■ TEMPERATURE RANGE: -40°C TO 125°C
