GENERAL DESCRIPTION
The SG2002/A series low-power, low-noise, low-dropout, CMOS linear voltage regulators operate from a 2.5V to 5.5V input and deliver up to 300mA. They are the perfect choice for low voltage, low power applications. An ultra low ground current (110µA at 300mA output) makes this part attractive for battery operated power systems. The SG2002/A series also offer ultra low dropout voltage (210mV at 300mA output) to prolong battery life in portable electronics. Systems requiring a quiet voltage source, such as RF applications, will benefit from the SG2002/A series’ ultra low output noise (30µVRMS). An external noise bypass capacitor connected to the device’s BP pin can further reduce the noise level.
