SG2010-1.5

SG2010 GENERAL DESCRIPTION The SG2010 low-power, low-dropout, CMOS linear voltage regulator operates from 2.5V to 5.5V input and delivers up to 150mA. It is the perfect choice for low voltage, low power applications. An ultra low ground current (100µA at 150mA output ) makes this part attractive for battery operated power systems. The SG2010 series also offers ultra low dropout voltage (105mV at 150mA output) to prolong battery life in portable electronics. The output voltage is preset to voltages in the range of 1.5V to 5.0V. Other features include foldback current limit and thermal shut-down protection. SG2010 comes in 3-pin SOT23 package and 3-pin SOT89 package. 150mA, Low Power, Low Dropout, Linear Regulators FEATURES - Ultra-Low Dropout Voltage: 105mV at 150mA output - Low 80µA No-Load Supply Current - Low 100µA Operating Supply Current - at 150mA Output Thermal-Overload Protection Output Current Limit Preset Output Voltages (±1.8% Accuracy) Output Voltage: Available in Fixed Outputs of 1.5V, 1.8V, 2.5V, 2.8V, 3.0V, and 3.3V PIN CONFIGURATIONS（TOP VIEW） SG2010 SG2010 GND APPLICATIONS Cellular Telephones Digital Cameras MP3、MP4 USB 2.0 Modems PC Cameras Hand-Held Instruments Electronic Dictionarys Portable/Battery-Powered Equipment GND 1 3 IN 1 OUT 2 GND 3 IN OUT 2 SOT23-3 SOT89-3 TYPICAL OPERATION CIRCUIT INPUT IN CIN 1μF OUT OUTPUT GND COUT 1μF Shengbang Microelectronics Co, Ltd Tel: 86/451/84348461 www.sg-micro.com REV.

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.
