LD3980 - STMicroelectronics

LD3980 Low drop - Low supply voltage Low ESR capacitor compatible

The LD3980 provides up to 300mA, from 1.7V to 3.6V input voltage. It can deliver a guaranteed 300mA continuous load current with a low 100mV dropout. It is stable with ceramic capacitor. The ultra low drop-voltage, low quiescent current and low noise makes it suitable for low power applications and in battery powered systems. High power supply rejection is .

Features

tained down to low input voltage levels common to battery operated circuits. Shutdown Logic Control function is available 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 device also includes a constant current limiting and thermal overload protection. Typical applications are in mobile phone, personal digital assistant (PDAs), cordless phone and similar battery powered wireless systems, portable information appliances..
