The SGM2228 a low noise, high accuracy, high PSRR and low dropout voltage linear regulator which is designed using CMOS technology. It provides 500mA output current capability. The operating input voltage range is from 2.7V to 20V. The adjustable output voltage range is from 1.2V to (VIN - VDROP).
Other features include under-voltage lockout, logic-controlled shutdown mode, current limit and thermal shutdown protection. The SGM2228 has automatic discharge function to quickly discharge VOUT in the disabled status.
The SGM2228 is available in Green WLCSP-0.95× 1.16-6B, TDFN-2×2-6AL and SOT-23-5 package. It operates over an operating temperature range of -40℃ to +125℃.
