Features ■ Input voltage from 2.5V to 6V ■ Stable with low ESR ceramic capacitors ■ Ultra low dropout voltage (100mV typ. at 150mA load, 0.4mV typ. at 1mA load) ■ Very low quiescent current (85μA typ. at no load, 170μA typ. at 150mA load; max 1.5μA in OFF mode) ■ Guaranteed output current up to 150mA ■ Wide range of output voltage: 1.22V; 1.8V; 2.5V;2.6V; 2.7V; 2.8V; 2.9V; 3V;3.3V;4.7V ■ Fast turn-on time: typ. 200μs [C O =1μF, C BYP = 10nF and I O =1mA] ■ Logic-controlled electronic shutdown ■ Internal current and thermal limit ■ Output low noise voltage 30μV RMS over 10Hz to 100KHz ■ S.V.R. of 60dB at 1KHz, 50dB at 10KHz ■ Temperature range: -40°C to 125°C Description The LD3985 provides up to 150mA, from 2.5V to 6V 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 10KHz. 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 LD3985 is designed to work with low ESR ceramic capacitors. Typical applications are in mobile phone and similar battery powered wireless systems.
