- Thermal-Overload Protection

- Output Current Limit

- 10nA Logic-Controlled Shutdown

- Available in Multiple Output Voltage Versions

Fixed Outputs of 1.5V, 1.8V, 2.5V, 2.8V, 2.85V,

3.0V, 3.3V

The SGM2015 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

SGM2015 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

SGM2015 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, foldback current limit and thermal shut-

down protection.

Devices come in 5-pin SOT23 package.
