The SGM2019 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 SGM2019 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 SGM2019
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
1.2V to 5.0V. Other features include a 10nA logiccontrolled
shutdown mode, foldback current limit and
thermal shutdown protection.资料下载
