Description
The LP2985-N low noise linear (LDO) regulator delivers up to 150-mA output current and only requires 300-mV dropout voltage of input to output. Using an optimized vertically integrated PNP (VIP) process, the LP2985-N delivers unequaled performance for all battery-powered designs. The LP2985-N device provides 1% tolerance precision output voltage with only 75-µA quiescent current at 1-mA load and 850 µA at 150-mA load. By adding a 10-nF bypass capacitor, the output noise can be reduced to 30 µVRMS in a 30-kHz bandwidth.
The LP2985-N is designed to work with a ceramic output capacitor with equivalent series resistance (ESR) as low as 5 mΩ. The device is available with fixed output voltage from 2.5 V to 6.1 V. Contact Texas Instrument Sales for specific voltage option needs.
For all available packages, see the orderable addendum at the end of the data sheet.Exact equivalent in functionality and parametrics to the compared device:
