GENERAL DEscriptION

The SGM2038 is a low noise, low dropout voltage linear regulator which is designed using CMOS technology. It provides 500mA output current capability. The operating input voltage range is from 0.8V to 5.5V and bias supply voltage range is from 2.5V to 5.5V. The output voltage range is from 0.8V to 3.6V.

Other features include logic-controlled shutdown mode, short-circuit current limit and thermal shutdown protection. The SGM2038 has automatic discharge function to discharge VOUT in the disabled status.

The SGM2038 is suitable for applications which need low noise, fast transient response and low IQ consumption, such as battery-powered e and smartphones, etc.

The SGM2038 is available in a Green UTDFN-1.2×1.2-4L package. It operates over an ambient temperature range of -40℃ to +125℃.
