SGM2039
Fast Transient Response, 1A, Low Noise, Low Voltage, Low Dropout Linear Regulator
Fast Transient Response, 1A, Low Noise, Low Voltage, Low Dropout Linear Regulator
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.
