A/CH www.taitroncomponents.com Page 18 of 23 300mA Ultra Low Dropout Voltage Regulator LD2210 Series Typical Applications Note 7: Dropout voltage is 250mV when TA=25oC. In order to obtain a normal output voltage, VOUT+0.25V is the minimum input voltage which will results a low PSRR, imposing a bad influence on system. Therefore, the recommended input voltage is VOUT+1V to 13.2V. For LD2210-3.0 version, its input voltage can be set from 4V(VOUT+1V) to 13.2V. Rev. A/CH www.taitroncomponents.com Page 19 of 23 300mA Ultra Low Dropout Voltage Regulator LD2210 Series Application Notes Input Capacitor A 1µF minimum capacitor is recommended to be place between VIN and GND. Output Capacitor It is required to prevent oscillation. 1.0µF minimum is recommended when CBYP is unused. 2.2µF minimum is recommended when CBYP is 100pF. The output capacitor may be increased to improve transient response. Noise Bypass Capacitor Bypass capacitor is connected to the internal voltage reference. A 100pF capacitor connected from BYP to GND make this reference quiet, resulting in a significant reduction in output noise, but the ESR stable area will be narrowed. The start-up speed of the LD2210 is inversely proportional to the value of reference bypass capacitor. In some cases, if output noise is not a major concern and rapid turn-on is necessary, omit C BYP and leave BYP open. Power Dissipation Thermal shutdown may take place if exceeding the maximum power dissipation in application. Under all possible operating conditions, the junction temperature must be within the range specified under absolute maximum ratings to avoid thermal shutdown. To determine if the power dissipated in the regulator reaches the maximum power dissipation (see figure 13, 14), using: TJ = PD*θJA + TA; PD=(VIN-VOUT)*IOUT+VIN*IGND Where: TJ≤TJ(max), TJ(max) is absolute maximum ratings for the junction temperature; VIN*IGND can be ignored due to its small value. TJ(max) is 150oC, θJA is 200oC/W, no heatsink is required since the package alone will dissipate enough heat to satisfy these requirements unless the calculated value for power dissipation exceeds the limit. Example (3.0V version): IOUT=300mA, TA=50oC, VIN(Max) is: (150oC-50oC)/(0.3A*200oC/W)+3.0V=4.67V Therefore, for good performance, please make sure that input voltage is less than 4.67V without heatsink when TA=50oC.
