The LTC1928ES6-5#TRPBF is a doubler charge pump with an integrated low-noise LDO linear regulator from Analog Devices (formerly Linear Technology). It converts a 2.7V to 4.4V input to a regulated 5V output at up to 30mA, with only 90uV RMS output noise. Packaged in a 6-lead TSOT-23, it is ideal for powering noise-sensitive devices such as VCOs and RF circuits.
