FEATURES
s s s s s s s s DESCRIPTIO s s Regulated Negative Voltage from a Single Positive Supply Low Output Ripple: Less Than 1mVP-P Typ High Charge Pump Frequency: 900kHz Small Charge Pump Capacitors: 0.1µF Requires Only Four External Capacitors Fixed – 4.1V, –2.5V, –2V or Adjustable Output Shutdown Mode Drops Supply Current to <1µA High Output Current: Up to 20mA (Depending on VCC to VOUT Range) Output Regulation: 2.5% Over Line, Load and Temperature Available in 8-Lead MSOP, 8-Lead Narrow SO and 16-Lead Narrow SSOP The LTC®1550L/LTC1551L are switched capacitor charge pump voltage inverters which include internal linear postregulators to minimize output ripple. The LTC1550L fixed output voltage versions include –4.1V, –2.5V and –2V with ripple voltages typically below 1mVP-P. The LTC1550L is also available in an adjustable output voltage version. The LTC1550L/LTC1551L are ideal for use as bias voltage generators for GaAs transmitter FETs in portable RF and cellular telephone applications.
