GENERAL DESCRIPTION

The SGM2084 is a CMOS, fast transient response, low

noise and high accuracy linear regulator. It is capable of

supplying 1A output current with typical dropout voltage

of only 145mV. The operating input voltage range is

from 1.5V to 5.5V. The fixed output voltage range is

from 0.55V to 4.2V and adjustable output voltage range

is from 0.55V to 5.0V.

Other features include an open-drain power-good (PG)

output, logic-controlled shutdown mode, short-circuit

current limit and thermal shutdown protection. The

SGM2084 has automatic discharge function to quickly

discharge VOUT in the disabled status.

The SGM2084 is available in a Green TDFN-2×2-6AL

package. It operates over an operating temperature

range of -40℃ to +125℃.
