SGM2217

1.5A, Low Dropout Positive Regulator

GENERAL DESCRIPTION

FEATURES

The SGM2217 is a low noise, high current and low

dropout voltage linear regulator. It is capable of

supplying 1.5A output current with typical dropout

voltage of 1.3V. The operating input voltage range is

from 2.8V to 30V. The fixed output voltages are 1.8V,

2.5V, 2.8V, 3.0V, 3.3V, 5.0V and 12V. The adjustable

output voltage range is from 1.25V to 26V.

● Wide Input Voltage Range: 2.8V to 30V

● Adjustable Output from 1.25V to 26V

● Fixed Outputs of 1.8V, 2.5V, 2.8V, 3.0V, 3.3V, 5.0V

and 12V

● 1.5A Maximum Output Current

● Low Dropout Voltage: 1.3V (TYP) at 1.5A

● Line Regulation: 0.04% (TYP)

● Load Regulation: 0.04% (TYP)

Other features include short-circuit current limit and

thermal shutdown protection.

● Current Limiting and Thermal Protection

● Excellent Load and Line Transient Responses

● Stable with Small Case Size Ceramic Capacitors

● -40℃ to +125℃ Operating Temperature Range

● Available in Green TO-263-3A and TDFN-4×4-8L

Packages
