Additional Infomation About Product

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 A 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 Features used as local regulator, it is possible to put a part Ultra low dropout voltage (0.17 V typ. at 100 of the board in standby, decreasing the total mA load, 7 mV typ. at 1 mA load) power consumption. The LD2981 is designed to Very low quiescent current (80 A typ. at no work with low ESR ceramic capacitor. Typical applications are in cellular phone, palmtop/laptop load in on mode max 1 A in off mode) computer, personal digital assistant (PDA), Guaranteed output current up to 100 mA personal stereo, camcorder and camera. 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 VRMS Temperature range: -40 to 125 C Small package SOT23-5L and SOT-89 Fast dynamic response to line and load changes April 2016 DocID6279 Rev 17 1/27 www.st.com This is information on a product in full production.
