SGM2005 Low Power, Low Dropout, 150mA, RF - Linear Regulators GENERAL DESCRIPTION FEATURES The SGM2005 series low-power, low-noise, low-dropout, CMOS linear voltage regulators operate from a 2.5V to 5.5V input and deliver up to 150mA. They are the perfect choice for low voltage, low power applications. An ultra low ground current ( 150µA at 150mA output ) makes these parts attractive for battery operated power systems. The SGM2005 series also offer ultra low dropout voltage (150mV at 150mA output) to prolong battery life in portable electronics. Systems requiring a quiet voltage source, such as RF applications, will benefit from the SGM2005 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. - Low Output Noise: 30µVRMS typ(10Hz to 100KHz) - Ultra-Low Dropout Voltage: 150mV at 150mA output - Low 77µA No-Load Supply Current - Low 150µA Operating Supply Current - at 150mA Output High PSRR: 73dB at 1KHz Thermal-Overload Protection Output Current Limit Preset Output Voltages (±2.7% Accuracy) 10nA Logic-Controlled Shutdown Available in Multiple Output Voltage Versions Fixed Outputs of 1.8V, 2.5V, 2.8V, 3.0V and 3.3V The output voltage is preset to voltages in the range of 1.5V to 5.0V.

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.
