ADM1052

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

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 con-trol 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.\n\nThe ADM1052 operates from a 12 V supply. This gives suffi-cientheadroom for the amplifiers to drive external N-channel MOSFETs, operating as source-followers, as the external series pass devices. This has the advantage that N-channel devices are cheaper than P-channel devices of similar performance, and the circuit is easier to stabilize than one using P-channel devices in a common-source configuration.\n\n
