SGM2019
Low Power, Low Dropout, RF Linear Regulator
Low Power, Low Dropout, RF Linear Regulator
GENERAL DESCRIPTION

The SGM2019 is a low power, low noise and low dropout voltage RF linear regulator. It is capable of supplying 300mA output current with typical dropout voltage of only 270mV. The operating input voltage range is from 2.5V to 5.5V. The fixed output voltage range is from 1.2V to 3.3V and the adjustable output voltage range is from 1.2V to 5.0V.

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

The SGM2019 is available in Green SOT-23-5 and SC70-5 packages. It operates over an operating temperature range of -40 to +85.
