Description

General part information

LD2980 Series

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 the INHIBIT pin is pulled low. A 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 LD2980 is designed to work with low ESR ceramic capacitors. Typical applications are cellular phone, laptop computer, personal digital assistant (PDA), personal stereo, camcorder and camera.Stable with low ESR ceramic capacitorsUltra low dropout voltage (0.12 V typ. at 50 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 50 mALogic-controlled electronic shutdownOutput voltage of 1.8; 3.0; 3.3; 5.0 VInternal current and thermal limit± 0.5% Tolerance output voltage available (A version)Output low noise voltage 160 µVRMSTemperature range: -40 to 125 °CSmallest package SOT23-5LFast dynamic response to line and load changes
