描述

• GM7130 series is designed to provide all the active functions for a step-down (buck) switching regulator and drives a maximum load current as high as 3A line and load regulations.
• GM7130 is available in fixed output voltages of 3.3V, 5V, and 12V and a versatile Adjustable output version.
• These regulators are simple to use and require a minimum number of external components.
• The features include internal frequency compensation and a fixed-frequency oscillator.
• The GM7130 is a high-efficiency replacement for popular three-terminal linear regulators and is requiring a smaller heat sink or even no need
  heat sink.
• GM7130 performs well with standard inductors from most manufacturers and simplifies the design of switch-mode power supplies.
• External shutdown is included with an 80 µA (typical) standby current.
• The output switch has cycle-by-cycle current limiting as well as thermal shutdown for full protection under fault conditions.
• GM7130 operates at a switching frequency of 52 kHz which allows smaller size filter components than what would be needed with
  lower frequency switching regulators.
• GM7130 series is available in standard 5-lead TO-220, TO220B, and TO263 packages.
