Product Overview
LD2981ABU50TR is an ultra low-drop voltage regulator with inhibit. It is a 100mA fixed-output voltage regulator. The low-drop voltage and the ultra-low quiescent current make it suitable for low-noise, low-power applications, and in battery-powered systems. The quiescent current in sleep mode is less than 1μA when the INHIBIT pin is pulled low. This means that when the device is used as a local regulator, it is possible to put a part of the board on standby, decreasing the total power consumption. It is designed to work with a low ESR ceramic capacitor. Typical applications are in cellular phones, palmtop/laptop computers, personal digital assistants (PDA), personal stereos, camcorders, and cameras.
- Logic-controlled electronic shutdown
- Internal current and thermal limit
- Fast dynamic response to line and load changes
- Operating input voltage range from 2.5 to 16V
- Quiescent current is 100µA typ (IO = 1mA, on mode), 0.8µA (VINH <lt/> 0.3V, off mode)
- Dropout voltage is 70mV typ (IO = 25mA)
- Supply voltage rejection is 63dB typ (CO = 10µF, f = 1KHz)
- Output noise voltage is 160µVRMS typ (BW = 300Hz to 50KHz, CO = 10µF)
- SOT-89 package
- Temperature range from -40 to 125°C
