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 1.2V 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. The ADM1052 operates from a 12V supply and features low quiescent current and low shutdown current.
The ADM1052 is a dual-channel precision voltage regulator controller designed for use in desktop computers, servers, and workstations. It contains two independent controllers on a single chip, each driving an external N-channel MOSFET to generate precise 2.525 V outputs with high accuracy over line, load, and temperature variations.
The device operates from a 12 V supply and includes features such as shutdown inputs for each channel, hiccup mode fault protection, and low quiescent current consumption. It is housed in an 8-lead SO package and requires no external voltage or current setting resistors.
