LTC1983ES6-5#pbf概述

    Product Introduction
    The LTC1983-3 and LTC1983-5 are inverting charge-pump DC/DC converters that generate regulated negative outputs. These devices are suitable for applications requiring precise negative voltages such as LCD bias supplies and GaAs FET bias supplies. They operate within a wide voltage range of 2.3V to 5.5V and can deliver up to 100mA of output current.
    Technical Parameters
    - Output Voltage: -3V (LTC1983-3) or -5V (LTC1983-5)
    - Current Capability: Up to 100mA
    - Input Voltage Range: 2.3V to 5.5V
    - Quiescent Current: 25µA typical
    - Shutdown Current: Less than 1µA
    - Shutdown Mode: Controlled via the SHDN pin
    - Operating Temperature Range: -40°C to 85°C
    - Package Type: 6-pin low-profile (1mm) ThinSOT
    Product Features and Advantages
    The LTC1983-3/LTC1983-5 offer several unique features:
    - Low Quiescent Current: Ensures minimal power consumption in active modes.
    - Zero Current Shutdown Mode: Programmable via the SHDN pin for enhanced power management.
