SG2001/A

GENERAL DESCRIPTION

The SG2001/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 150mA. They are the perfect choice

for low voltage, low power applications. An ultra low

parts attractive for battery operated power systems. The

SG2001/A series also offer ultra low dropout voltage

(105mV at 150mA output) to prolong battery life in

portable electronics. Systems requiring a quiet voltage

source, such as RF applications, will benefit from the

SG2001/A series’ ultra low output noise (30µVRMS). 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 1.2V

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

down protection.

Devices come in 5-pin SOT23 package.
