GENERAL DESCRIPTION

The SGM2039 is a low noise, low voltage, fast transient

response and low dropout voltage linear regulator

which is based on CMOS technology and it provides 1A

output current capability. The operating input voltage

range is from 1.8V to 5.5V. The fixed output voltage

range is from 0.8V to 4.2V and adjustable output

voltage range is from 0.8V to 5.0V.

Other features include logic-controlled shutdown mode,

short-circuit current limit and thermal shutdown

protection. The SGM2039A has automatic discharge

function to quickly discharge VOUT in the disabled status.

The SGM2039 is suitable for various applications which

need low noise and fast transient response power

supply, such as power supply of camera module in

smart phones. Fixed or adjustable output voltage

versions are provided.

The SGM2039 is available in a Green XTDFN-1.6×1.2-8L

package. It operates over an operating temperature

range of -40℃ to +125℃.
