• Manufacturer Part Number: GM7130-12A5R
• Description: 3A STEP DOWN VOLTAGE SWITCHING REGULATORS
• Manufacturer: GAMMA [Gamma Microelectronics Inc.]

Note 1: Stresses greater than those listed under Maximum Ratings may cause permanent damage to
Note 2: The human body model is a 100pF capacitor discharge through a 1.5KΩ resistor into each pin.
Note 3: External components such as the catch diode, inductor, input and output capacitors, and voltage
Note 4: No diode, inductor or capacitor connected to output pin.
Note 5: Feedback pin removed from output and connected to 0V to force the output transistor switch ON.
Note 6: Feedback pin removed from output and connected to 12V for the 3.V, 5V and Adj version, to
