GENERAL DESCRIPTION

The SGM2077B is an ultra-high PSRR, fast transient

response, low noise and low dropout voltage linear

regulator which is designed using CMOS technology. It

provides 1.5A 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 1.2V logic-controlled shutdown

mode, short-circuit current limit and thermal shutdown

protection. The SGM2077B has automatic discharge

function to quickly discharge VOUT in the disabled status.

The SGM2077B is available in a Green

WLCSP-0.8×1.2-6B-B package. It operates over an

operating temperature range of -40℃ to +125℃.
