Product Summary
The LTC1550LIGN#TR is a switched capacitor charge pump voltage inverter which includes internal linear post-regulators to minimize output ripple. Output voltages are fixed at -4.1V, -2.5V and -2V with ripple voltages typically below 1mVP-P. The LTC1550LIGN#TR is also available in an adjustable output voltage version. The device is ideal for use as bias voltage generators for GaAs transmitter FETs in portable RF and cellular telephone applications. The applications of the LTC1550LIGN#TR include GaAs FET Bias Generators, Negative Supply Generators, Battery-Powered Systems, Single Supply Applications.
