Features & Applications
The LDS3985M30R provides up to 300 mA, from 2.5 V to 6 V input voltage. It is stable with ceramic and high quality tantalum capacitor. The ultra low drop voltage, low quiescent current and low noise makes it suitable for low power applications and in battery powered systems. Regulator ground current increases only slightly in dropout, further prolonging the battery life.

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.

Features:

  • Input voltage from 2.5 V to 6 V
  • Stable with low ESR ceramic capacitors
  • Ultra low dropout voltage (150 mV typ. at 300 mA load, 0.4 mV typ. at 1 mA load)
  • Very low quiescent current (85 μA typ. at no load, 200 μA typ. at 300 mA load; max 1.5 μA
  • in off mode)
  • Guaranteed output current up to 300 mA
  • Wide range of output voltage:
    • from 1.25 V to 5.0 V
  • Fast turn-on time: typ. 240 μs
    • [CO= 2.2 μF, CBYP = 33 nF and IO = 1 mA]
  • Logic-controlled electronic shutdown
  • Internal current and thermal limit
  • Output low noise voltage 30 μVRMS over 10 Hz to 100 kHz
  • SVR of 55 dB at 1 kHz, 50 dB at 10 kHz
  • Temperature range: -40 °C to 125 °C

Applications:

  • Mobile phone
  • Battery powered wireless systems
  • Portable information appliances
