LTC1550/LTC1551 Low Noise, Switched Capacitor Regulated Voltage Inverters FEATURES s s s s s s s s s s DESCRIPTION The LTC®1550/LTC1551 are switched capacitor charge pump voltage inverters which include internal linear postregulators to minimize output ripple. Output voltages are fixed at – 4.1V, with ripple voltages typically below 1mVP-P. The LTC1550 is also available in an adjustable output voltage version. The LTC1550/LTC1551 are ideal for use as bias voltage generators for GaAs transmitter FETs in portable RF and cellular telephone applications. The LTC1550/LTC1551 operate from single 4.5V to 6.5V supplies and draw typical quiescent currents of 4.25mA with a 5V supply. Each device includes a TTL compatible Shutdown pin which drops supply current to 0.2µA typically.
