Low Dropout, Linear Regulators

FEATURES

GENERAL DESCRIPTION

- Low Output Noise: 30µVRMS typ(10Hz to 100KHz)

- Ultra-Low Dropout Voltage:

The SG2003/A and SG2004/A low-power, low-noise,

low-dropout, CMOS linear voltage regulators operate from

a 2.5V to 5.5V input and deliver up to 400mA (400mA peak

SG2003 only). They are the perfect choice for low voltage,

low power applications. An ultra low ground current

(120µA at 400mA output) make them attractive for battery

operated power systems. The SG2003/A and SG2004/A

series also offer ultra low dropout voltage (280mV at

400mA output) to prolong battery life in portable

electronics. Systems requiring a quiet voltage source, such

as RF applications, will benefit from the SG2003/A and

SG2004/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.

280mV at 400mA output

- Low 77µA No-Load Supply Current

- Low 120µA Operating Supply Current

at 400mA Output

- Thermal-Overload Protection

- Output Current Limit

- Preset Output Voltages (±1.6% Accuracy)

- 10nA Logic-Controlled Shutdown

- Available in Multiple Output Voltage Versions

Fixed Outputs of 2.5V, 2.8V, 2.85V, 3.0V, and 3.3V

Adjustable Output from 1.5V to 4.5V

The output voltage is preset to voltages in the range of 1.5V

to 4.5V. Other features include a 10nA logic-controlled

shutdown mode, foldback current limit and thermal

shut-down protection.
