GENERAL DEscriptION
The SGM2051 is an ultra-high PSRR, fast transient response, low noise and low dropout voltage linear regulator which is designed using CMOS technology. It provides 1.2A output current capability. The operating input voltage range is from 0.5V to 5.5V and bias supply voltage range is from 2.5V to 5.5V. The adjustable output voltage range is from 0.5V to 3.3V.
Other features include logic-controlled shutdown mode, short-circuit current limit and thermal shutdown protection. The SGM2051 has automatic discharge function to quickly discharge VOUT in the disabled status.
The SGM2051 is available in a Green WLCSP-0.8×1.2-6B-A package. It operates over an operating temperature range of -40℃ to +125℃.
