SGM2007/A

GENERAL DESCRIPTION

The SGM2007/A series low-power, low-noise, low-dropout,

CMOS linear voltage regulators operate from a 2.5V to 5.5V

input and deliver up to 300mA. They are the perfect choice

for low voltage, low power applications. An ultra low

ground current（200

µA

at 300mA output ) makes these part

attractive for battery operated power systems. The

SGM2007/A series also offer ultra low dropout voltage

(300mV at 300mA output) to prolong battery life in

portable electronics. Systems requiring a quiet voltage

source, such as RF applications, will benefit from the

SGM2007/A series’ ultra low output noise (30µVRMS) and

high PSRR. An external noise bypass capacitor connected

to the device’s BP pin can further reduce the noise level.

The output voltage is preset to voltages in the range of 1.5V

to 5.0V. Other features include a 10nA logic-controlled

shutdown mode,

foldback current limit

and thermal shut-

down protection.

Devices come in 5-pin SOT23 package.
