SGM2030 Low Power, Low Dropout,RF Linear Regulator
GENERAL DESCRIPTION
The SGM2030 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.
Other features include logic-controlled shutdown mode,
output current limit and thermal shutdown protection.
The SGM2030 is suitable for application which needs
low noise and low power supply, such as MP3 players,
palmtop computers, etc.
The SGM2030 is available in a Green UTDFN-1.2×1.6-4L
package. It operates over an operating temperature
range of -40℃ to +85℃.
