LDLN015xx is an ultra low noise linear regulator which provides 150mA maximum current from an input voltage ranging from 2.1 V to 5.5 V with a typical dropout voltage of 86 mV. The LDLN015xx provides a very clean output suitable for ultra sensitive loads with its 6.3µVRMS noise value in a band from 10 Hz to 100 kHz. It is stable with ceramic capacitors and suitable for low power battery powered applications.
The LDLNO15xx is an ultra-low noise linear regulator designed for battery-powered applications requiring clean power for sensitive loads like ADCs and VCOs. It provides a maximum output current of 150 mA with a typical dropout voltage of 86 mV and operates with an input voltage range of 2.1 V to 5.5 V.
Key features include a very low noise level of 6.3 µVrms (10 Hz to 100 kHz), high power supply rejection ratio (PSRR) exceeding 90 dB at low frequencies, and a logic-controlled electronic shutdown mode. The device is available in a compact 2 x 2 mm DFNG package and operates over a temperature range of -40 °C to 125 °C.
