The SGM2014 series low-power, low-noise, low-dropout,
CMOS linear voltage regulators operate from a 2.5V to
5.5V input and deliver up to 250mA. They are the
perfect choice for low voltage, low power applications.
An ultra low ground current(160µA at 250mA output )
makes these part attractive for battery operated power
systems. The SGM2014 series also offer ultra low
dropout voltage (250mV at 250mA output) to prolong
battery life in portable electronics. Systems requiring a
quiet voltage source, such as RF applications, will
benefit from the SGM2014 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
1.5V to 3.3V. Other features include a 10nA
logic-controlled shutdown mode, output current limit
and thermal shut- down protection.
Devices come in 5-pin SOT23 package.
