ADM1052JR中文资料亚德诺数据手册PDF规格书

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.
