SGM2031
Low Power, Low Dropout, RF Linear Regulator
Low Power, Low Dropout, RF Linear Regulator
GENERAL DESCRIPTION

The SGM2031 is a low power and low dropout voltage RF linear regulator. It is capable of supplying 250mA output current with typical dropout voltage of only 230mV. The operating input voltage range is from 2.5V to 5.5V. The fixed output voltage range is from 1.2V to 3.3V.

Other features include logic-controlled shutdown mode, output current limit and thermal shutdown protection.

The SGM2031 is available in a Green UTDFN-1×1-4L package. It operates over an operating temperature range of -40 to +85.
