The LTC1682IS8 from LT is a versatile doubler charge pump integrated circuit designed with an internal low noise, low dropout (LDO) linear regulator. This device is engineered to provide a low noise boosted supply voltage, making it suitable for noise-sensitive applications such as high frequency VCOs in wireless communications.
Key electrical specifications include a low output noise of 60mVRMS (100kHz BW), an adjustable output voltage range from 2.5V to 5.5V, and fixed output options of 3.3V and 5V. The charge pump operates with a wide input voltage range of 1.8V to 4.4V and can deliver an output current of up to 50mA. It utilizes small ceramic capacitors and requires no inductors, simplifying board design. The switching frequency is 550kHz, with low operating current of 150mA and a low shutdown current of 1mA.
Internal protection features include thermal shutdown and current limiting. The LTC1682IS8 is available in an 8-pin SOIC package, designed for surface mount applications. Its ability to provide a regulated, low noise output makes it ideal for powering sensitive components in portable medical instruments, wireless PCMCIA cards, and cellular phones.
