1 GENERAL DESCRIPTION The SGM2019 series low-power, low-noise, low-dropout, CMOS linear voltage regulators operate from a 2.5V to 5.5V input voltage. They are the perfect choice for low voltage, low power applications. A low ground current makes this part attractive for battery operated power systems. The SGM2019 series also offer ultra low dropout voltage to prolong battery life in portable electronics. Systems requiring a quiet voltage source, such as RF applications, will benefit from the SGM2019 series ultra low output noise (30µV RMS ) and high PSRR. An external noise bypass capacitor connected to the device s BP pin can further reduce the noise level. FEATURES Low Output Noise Low Dropout Voltage Thermal-Overload Protection Output Current Limit High PSRR (74dB at 1kHz) 10nA Logic-Controlled Shutdown Available in Multiple Output Voltage Versions Fixed Outputs of 1.2V, 1.5V, 1.8V, 2.5V, 2.6V, 2.8V, 2.85V, 3.0V and 3.3V Adjustable Output from 1.2V to 5.0V -40 to +85 Operating Temperature Range Available in Green SC70-5 and SOT-23-5 Packages The output voltage is preset to voltages in the range of 1.2V to 5.0V. Other features include a 10nA logiccontrolled shutdown mode, foldback current limit and thermal shutdown protection. The SGM2019 is available in Green SOT-23-5 and SC70-5 packages. It operates over an ambient temperature range of -40 to +85.

The location of pin 1 on the YJxx is determined by orienting the package marking as shown. 2. xx is the output voltage code. (For Example: when the output voltage is 1.8V, it is expressed as 18.) CAUTION This integrated circuit can be damaged by ESD if you don t pay attention to ESD protection. SGMICRO recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. SGMICRO reserves the right to make any change in circuit design, specification or other related things if necessary without notice at any time. Please contact SGMICRO sales office to get the latest datasheet.

11 APPLICATION NOTE When LDO is used in handheld products, attention must be paid to voltage spikes which could damage SGM2019. In such applications, voltage spikes will be generated at charger interface and V BUS pin of USB interface when charger adapters and USB equipments are hot-plugged. Besides this, handheld products will be tested on the production line without 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 spikes will be generated at the battery connector. The voltage spikes will be very high, and 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 spikes in cell phone designs. The schematic is shown below.
