max889The MAX889 is a hh-frequency, regulated, 200mA, inverting charge pump that delivers a negative output voltage from a positive input. It has an adjustable output range, a logic-controlled shutdown mode, and a 0.1µA quiescent current.MAX889 includes soft-start, shutdown control, short-cir-cuit, and thermal protection. The oscillator, control circuitry, and four power MOSFET. switches are included on-chip. The charge pump
