SGM2031

Low Power, Low Dropout,

RF - Linear Regulators

GENERAL DESCRIPTION

The SGM2031 series low-power, low-dropout, CMOS

linear voltage regulators operate from a 2.5V to 5.5V

input voltage in an ultra small package. They are the

perfect choice for low voltage, low power applications. A

low ground current makes this part attractive for battery

operated power systems. The SGM2031 series also offer

ultra low dropout voltage to prolong battery life in portable

electronics. Systems requiring a quiet voltage source,

such as RF applications, will benefit from the SGM2031

series’ low output noise and high PSRR.

Other features include a 10nA logic-controlled shutdown

mode, foldback current limit and thermal shut-down

protection.

The SGM2031 is available in Green UTDFN-1×1-4L

package. It operates over an ambient temperature range

of -40°C to +85°C.
