SGM2032

Low Power, Low Dropout,

RF Linear Regulators

GENERAL DESCRIPTION

The SGM2032 series low-power, low-noise, low-dropout,

CMOS linear voltage regulators operate from a 2.5V to

5.5V input voltage. 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 SGM2032 series also offer low dropout

voltage to prolong battery life in portable electronics.

Systems requiring a quiet voltage source, such as RF

applications, will benefit from the SGM2032 series’ ultra

low output noise 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

0.9V

to

5.0V.

Other

features

include

a

10nA

logic-controlled shutdown mode, output current limit and

thermal shutdown protection.

The SGM2032 is available in Green SOT-23-5 and

SC70-5 packages. It operates over an ambient

temperature range of -40

℃ to +85℃.
