LD3985G29R规格书详情
Description
The LD3985xx provides up to 150 mA, from 2.5 V to 6 V input voltage. The ultra low drop-voltage, low quiescent current and low noise make it suitable for low power applications and in battery powered systems. Regulator ground current increases only slightly in dropout, further prolonging the battery life. Power supply rejection is better than 60 dB at low frequencies and starts to roll off at 10 kHz. High power supply rejection is maintained 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 LD3985xx is designed to work with low ESR ceramic capacitors. Typical applications are in mobile phone and similar battery powered wireless systems.
