SG2003/A SG2004/A 400mA, Low Power, Low Noise, Low Dropout, Linear Regulators GENERAL DESCRIPTION FEATURES 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. - Low Output Noise: 30µVRMS typ(10Hz to 100KHz) - Ultra-Low Dropout Voltage: 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. - 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 PIN CONFIGURATIONS（TOP VIEW） SG2003/A SG2003/A comes in 5-pin SOT23 package and SG2004/A comes in 8-pin SO package.

In such applications, voltage spike will be generated at changer interface and VBUS pin of USB interface when changer adapters and USB equipments are hot-inserted. Besides this, handheld products will be tested on the production line on the condition of no battery. Test Engineer will apply power from the connector pin which connects with positive pole of the battery. When external power supply is turned on suddenly, the voltage spike will be generated at the battery connector. The voltage spike will be very high, it always exceeds the absolute maximum input voltage (6.0V) of LDO. In order to get robust design. Design Engineer needs to clear up this voltage spike. Zener diode is a cheap and effective solution to eliminate such voltage spike. For example, BZM55B5V6 is a 5.6V small package Zener diode which can be used to remove voltage spike in cell phone design.
