Product Summary
The LTC1682IS8-3.3#TR is a doubler charge pump with an internal low noise, low dropout (LDO) linear regulator. The part is designed to provide a low noise boosted supply voltage for powering noise sensitive devices such as high frequency VCOs in wireless applications. An internal doubler charge pump converts a 1.8V to 4.4V input to a boosted output, while the internal LDO regulator converts the boosted voltage to a low noise regulated output. The applications of the LTC1682IS8-3.3#TR include VCO Power Supplies in Cellular Phones, 2-Way Pagers, Wireless PCMCIA Cards, Portable Medical Instruments, Low Power Data Acquisition, Remote Transmitters.
