SGM2019
Low Power, Low Dropout,
RF-Linear Regulators
GENERAL DESCRIPTION
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 (30µV_RMS) and high PSRR.
An external noise bypass capacitor connected to the
device’s BP pin can further reduce the noise level.
FEATURES

 Available in Multiple Output Voltage Versions
 Fixed Outputs of 1.2V, 1.5V, 1.8V, 2.5V, 2.6V, 2.8V,
2.85V, 3.0V and 3.3V
 Adjustable Output from 1.2V to 5.0V
 -40℃ to +85℃ Operating Temperature Range
 Available in Green SC70-5 and SOT-23-5 Packages
The output voltage is preset to voltages in the range of
1.2V to 5.0V. Other features include a 10nA logic-
controlled shutdown mode, foldback current limit and
thermal shutdown protection.
The SGM2019 is available in Green SOT-23-5 and
SC70-5 packages. It operates over an ambient
temperature range of -40℃ to +85℃.
