A/LX www.taitroncomponents.com Page 16 of21 150mA Ultra Low Dropout Positive Voltage Regulator LD2202 Typical Application (Note8) Note8:Dropuout voltage is 165mV when TJ=25°C.In order to obtain a normal output voltage,VO+0.165V is the minimum input voltage which will result in a low PSRR, imposing a bad influence on system. Therefore, the recommended input voltage is VO+0.5V to 13.2V.For LD2202-2.8 Version, Its input voltage can be set from 3.3V (VO+0.5V) to 13.2V.For the Adj version, any value from VO+0.5V to 13.2V is available.R1 and R2 must be correctly selected when setting the output voltage. For example, if 3.0V output voltage is required,R1and R2 Can be set to 10KΩ an 14 KΩ respectively. For Adj version, we recommend 2.3V as minimum output voltage. Rev. A/LX www.taitroncomponents.com Page 17 of21 150mA Ultra Low Dropout Positive Voltage Regulator LD2202 Application Notes Input Capacitor A1uF minimum capacitor is recommended to be place between VIN and GND Output 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 LD2202 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 CBYP and BYP open. Power Dissipation Thermal shutdown may occur if exceeding the maximum power dissipation 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 (Fig9 and Fig10), the formula is:TJ=TA+PD*θJA; PD=(VIN-VO)*IO+VIN*IGND. Where: TJ≤TJ (max) is absolute maximum rating for the junction temperature; VIN*IGND can be ignored due to the small value. TJ (max) is 150°C, θJA is 200°C/W for SOT-23-5 package and 165°C/W for SOT-89 package, no heat-sink 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: For 2.8V version packaged in SOT-23-5, IO=150mA,TA=30°C, VIN(max) =(150°C-30°C)/(0.15A*200°C/W)+2.8V=6.8V, therefore ,for good performance, please make sure that input voltage is less than 6.8V without heat-sink when TA=30°C, Rev.
