onsemi NCP3985
The NCP3985 is 150 mA LDO that provides the engineer with a very stable, accurate voltage with low noise and high Power Supply Rejection Ratio (PSRR) suitable for sensitive applications. The NCP3985 is stable with small, low value capacitors and is available in TSOP-5 package. In order to optimize performance for battery operated portable applications, the NCP3985 employs an advanced BiCMOS process to combine the benefits of low noise and superior dynamic performance of bipolar elements with very low ground current consumption at full loads offered by CMOS.| Part No. | NCP3985 |
