Offering a typical output noise voltage of just 38μVrms (at 2.5V and 10mA outputs), the LDOs provide a typical high ripple rejection of 70dB. An 80mV load transient response for output current changes between 1 and 300mA further contributes to the devices’ performance.
Despite the small 1.0×1.0x0.58mm DFN4 package, the series offers typical drop out voltages of just 210mV (at 2.5V and 300mA outputs). Integrated features include inrush current protection, overcurrent protection, thermal shutdown protection and a built in output auto-discharge function, all enabling optimised system performance with respect to noise and battery lifetime, as well as a reduced demand for external components.
This 300mA regulator is also available as the TCR3DF family in a general purpose SOT-25 package that makes it suitable for standard industrial and consumer applications.
