SGM2019
Low Power, Low Dropout,
RF - Linear Regulators
GENERAL DESCRIPTION
FEATURES
The SGM2019 series low-power, low-noise, low-dropout,
Low Output Noise
CMOS linear voltage regulators operate from a 2.5V to
Low Dropout Voltage
5.5V input voltage. They are the perfect choice for low
Thermal-Overload Protection
voltage, low power applications. A low ground current

makes this part attractive for battery operated power
High PSRR (68dB at 1kHz)
systems. The SGM2019 series also offer ultra low
10nA Logic-Controlled Shutdown
dropout voltage to prolong battery life in portable

electronics. Systems requiring a quiet voltage source,
Fixed Outputs of 0.9V, 1.2V, 1.3V, 1.5V, 1.8V, 2.1V,
such as RF applications, will benefit from the SGM2019
2.5V, 2.6V, 2.7V, 2.8V, 2.85V, 2.9V, 3.0V, 3.1V,
series’ ultra low output noise (30µVRMS) and high PSRR.
3.2V, 3.3V, 3.6V, 4.2V, 5.0V
An external noise bypass capacitor connected to the
Adjustable Output from 0.8V to 5.0V
device’s BP pin can further reduce the noise level.
-40℃ to +85℃ Operating Temperature Range
Green SC70-5 and SOT23-5 Packages
The output voltage is preset to voltages in the range of
0.8V to 5.0V. Other features include a 10nA logiccontrolled shutdown mode, foldback current limit and
thermal shut-down protection.
The SGM2019 has Green SC70-5 and SOT23-5
packages. It operates over an ambient temperature range
of -40°C to +85°C.
