GENERAL DESCRIPTION
The ADM1052 is a dual, precision, voltage regulator controller intended for power rail generation and active bus termination on personal computer motherboards. It contains a precision 1.2 V bandgap reference and two channels consisting of control amplifiers driving external power devices. Each channel has a shutdown input to turn off amplifier output and “Hiccup Mode” protection circuitry for the external power device.

    Two Independent Controllers on One Chip
    Two 2.525 V Outputs
    Shutdown Inputs to Control Each Channel
    ±2.5% Accuracy Over Line, Load, and Temperature
    Low Quiescent Current
    Low Shutdown Current
    Works with External N-Channel MOSFETs for Low Cost
    “Hiccup Mode” Fault Protection
    No External Voltage or Current Setting Resistors
    Small, 8-Lead SO Package
