SGM2014

功能特点

产品名称：Low Power Low Dropout 250mA RF - Linear Regulators 250mA单通道LDO

产品型号：SGM2014

产品描述：

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 Green SOT-23-5 package
