LP3905SD-00 - Brand New Texas Instruments Power Management Specialized - PMIC
-
Description
The LP3905SD-00 is a power management integrated circuit (PMIC) designed for portable RF and wireless applications, particularly in battery-powered systems. It is optimized for delivering ultra-low noise and low quiescent current, making it suitable for devices with demanding performance and space requirements. The LP3905SD-00 features a noise bypass pin for further reduction of output noise and works with low-ESR ceramic capacitors, minimizing board space usage. It has a shutdown mode with a standby current of less than 0.01µA and a fast turn-on time of less than 50µs. Available in a 5-lead SC-70 package, the LP3905SD-00 also offers high output accuracy, current limiting protection, and high ripple rejection ratio.
