GENERAL DESCRIPTION

The SGM2080 is a CMOS, fast transient response, low

noise and high accuracy linear regulator. It is capable of

supplying 500mA output current with typical dropout

voltage of only 70mV. 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

SGM2080 has automatic discharge function to quickly

discharge VOUT in the disabled status.

The SGM2080 is available in a Green TDFN-2×2-6AL

package. It operates over an operating temperature

range of -40℃ to +125℃.
