GENERAL DESCRIPTION

The SGM2033 is an ultra-low noise, low VIN, high

PSRR, high accuracy and low dropout voltage linear

regulator which is designed using CMOS technology. It

provides 250mA output current capability. The

operating input voltage range is from 1.8V to 5.5V and

output voltage range is from 1.2V to 5.0V.

Other features include logic-controlled shutdown mode,

short-circuit current limit and thermal shutdown

protection. The SGM2033 has automatic discharge

function to quickly discharge VOUT in the disabled status.

The SGM2033 is suitable for application which needs

low noise and fast transient response power supply,

such as power supply of camera module in smart

phone, etc.

The SGM2033 is available in Green SOT-23-5 and

UTDFN-1×1-4AL packages. It operates over an

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