The LTC1682CMS8-3.3 is a versatile doubler charge pump IC from Linear Technology (LT) designed to deliver a low noise, regulated output voltage. It combines an internal doubler charge pump with a low dropout (LDO) linear regulator, making it ideal for powering noise-sensitive devices such as high-frequency VCOs in wireless applications.
This device operates with a wide input voltage range from 1.8V to 4.4V. The output voltage is adjustable from 2.5V to 5.5V, with fixed output options of 3.3V and 5V available. It can supply an output current of up to 50mA. The charge pump operates at a switching frequency of 550kHz, utilizing small ceramic capacitors to minimize board space. The low output noise is specified at 60mVRMS (100kHz BW).
Key features include internal thermal shutdown and current limiting for protection. The device is available in an 8-pin MSOP or SO package, suitable for surface mount applications. Shutdown mode reduces supply current to less than 5mA and discharges the output to ground.
