Exposure to absolute maximum rating conditions for extended periods may affect reliability. Functional operation of the device at any conditions beyond those indicated in the Recommended Operating Conditions section is not implied. ESD SENSITIVITY CAUTION This integrated circuit can be damaged if ESD protections are not considered carefully. 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 even small parametric changes could cause the device not to meet the published specifications.

A 1μF or greater X7R or X5R ceramic capacitor is selected to get good dynamic performance. When VIN is required to provide large current instantaneously, a large effective input capacitor is required. Multiple input capacitors can reduce the impact from input trace inductance. Adding more input capacitors is available to restrict the ringing and to keep it below the device absolute maximum ratings. For COUT with larger capacitance, it is recommended to choose the larger capacitance CIN. Output Capacitor Selection (COUT) One or more output capacitors are required to maintain the stability of the LDO, and the output capacitors should be placed as close as possible to the OUT pin. In addition, in order to obtain the best transient performance, it is recommended to use X7R and X5R ceramic capacitors as output capacitors. Ceramic capacitors have low equivalent series resistance (ESR), excellent temperature and DC bias characteristics. However, it cannot be ignored that the effective capacitance of ceramic capacitors is affected by temperature, DC bias and package size. For example, Figure 6 shows the capacitance and DC bias and temperature characteristics of 0805, 10V, 10μF±10%, X7R capacitor. Therefore, it is necessary to evaluate whether the effective capacitance of the output capacitor can meet the stability requirements of the LDO in practical applications. In general, a capacitor in higher voltage rating and a larger package exhibits better stability, and the effective capacitance can be obtained from the manufacturer datasheet. SG Micro Corp www.sg-micro.com Capacitance Change Rate with DC Bias (%) The SGM2053S provides an EN pin as an external chip enable control to enable/disable the device.

(℃) The SGM2053S is a low input voltage, low noise and low dropout LDO and provides 500mA output current. These features make the device a reliable solution to solve many challenging problems in the generation of clean and accurate power supply. The high performance also makes the SGM2053S useful in a variety of applications. The SGM2053S provides the protection functions for output overload, output short-circuit condition and overheating. Figure 6. Capacitance vs. DC Bias and Temperature Characteristics The SGM2053S requires a minimum effective capacitance of 1μF for COUT to ensure stability. Additionally, COUT with larger capacitance and lower ESR will help increase the high frequency PSRR and improve the load transient response. Adjustable Regulator The output voltage of the SGM2053S-ADJ can be adjusted from 0.8V to 5.0V. The ADJ pin will be connected to two external resistors as shown in Figure 7, the output voltage is determined by the following equation:  R1  V= VADJ ×  1+  OUT  R2  (1) where: VOUT is output voltage and VADJ is the internal voltage reference, VADJ = 0.8V. One parallel capacitor (CFF) with R1 can be used to improve the feedback loop stability and PSRR, increase the transient response and reduce the output noise. Use R2 = 160kΩ to maintain a 5μA minimum load. VIN 1.6V to 5.5V IN CIN 1μF ON OUT ADJ SGM2053SADJ OFF EN BP GND VOUT CFF VADJ = 0.8V R1 R2 COUT 4.7μF CBP 22nF Figure 7. Adjustable Output Voltage Application (SOT-23-6 Version) DECEMBER 2024 11 500mA, Ultra-Low Dropout, Low Power, RF Linear Regulator SGM2053S APPLICATION INFORMATION (continued) Enable Operation The EN pin of the SGM2053S is used to enable/disable its device and to deactivate/activate the output automatic discharge function. When the EN pin voltage is lower than 0.4V, the device is in shutdown state. There is no current flowing from IN to OUT pins. In this state, the automatic discharge transistor is active to discharge the output voltage through a 70Ω (TYP) resistor. When the EN pin voltage is higher than 1.5V, the device is in active state. The output voltage is regulated to the expected value and the automatic discharge transistor is turned off. The EN pin is pulled down by an internal pull-down resistor when the EN pin is floated. This resistance will ensure the SGM2053S in shutdown state and reduce the power dissipation in system. Reverse Current Protection The power transistor has an inherent body diode. This body diode will be forward biased when VOUT > (VIN + 0.3V). When VOUT > (VIN + 0.3V), the reverse current flowing from the OUT pin to the IN pin will damage the SGM2053S. If VOUT > (VIN + 0.3V) event would happen in system, one external Schottky diode will be added between OUT pin and IN pin in circuit design to protect the SGM2053S. External Diode Negatively Biased Output When the output voltage is negative, the chip may not start up due to parasitic effects. Ensure that the output is greater than -0.3V under all conditions. If negatively biased output is excessive and expected in the application, a Schottky diode can be added between the OUT pin and GND pin.

Negatively Biased Output Application Output Current Limit and Short-Circuit Protection When overload events happen, the output current is internally limited to 730mA (TYP). When the OUT pin is shorted to ground, the short-circuit protection will limit the output current to 380mA (TYP). Thermal Shutdown When the die temperature exceeds the threshold value of thermal shutdown, the SGM2053S will be in shutdown state and it will remain in this state until the die temperature decreases to +140℃.

Reverse Protection Reference Design SG Micro Corp www.sg-micro.com Power dissipation (PD) of the SGM2053S can be calculated by the equation PD = (VIN - VOUT) × IOUT. The maximum allowable power dissipation (PD(MAX)) of the SGM2053S is affected by many factors, including the difference between junction temperature and ambient temperature (TJ(MAX) - TA), package thermal resistance from the junction to the ambient environment (θJA), the rate of ambient airflow and PCB layout. PD(MAX) can be approximated by the following equation: PD(MAX) = (TJ(MAX) - TA)/θJA (2) DECEMBER 2024 12 SGM2053S 500mA, Ultra-Low Dropout, Low Power, RF Linear Regulator REVISION HISTORY NOTE: Page numbers for previous revisions may differ from page numbers in the current version.
