tm TE CH T6330A 1A Low Dropout Voltage Regulator FEATURES • Wide Input Range: 2.5V to 5.5V • Available Output Voltages: 1.5/1.8/2.0/2.5/2.8/3.0/3.3/3.7V • Low-Noise for RF Application • Quick Start-Up (Typically 50us) • Fast Response in Line/Load Transient • Standby Current : 10uF on the T6330A input and the amount of capacitance can be increased without limit. The input capacitor must be located a distance of not more than 0.5 inch from the input pin of the IC and returned to a clean analog ground. Any good quality ceramic or tantalum can be used for this capacitor. The capacitor with larger value and lower ESR (equivalent series resistance) provides better PSRR and linetransient response. The output capacitor must meet both requirements for minimum amount of capacitance and ESR in all voltage regulator application. The T6330A is designed specifically to work with low ESR ceramic output capacitor in space-saving and performance consideration. Using a ceramic capacitor whose value is at least 10uF with ESR is more than 20mΩ on the T6330A output ensures stability. The T6330A still works well with output capacitor of other types due to the wide stable ESR range. Output capacitor of larger capacitance can reduce noise and improve load transient response, stability and PSRR.The output capacitor should be located with in 0.5 inch from the VOUT pin of the T6330A and returned to a clean analog ground. Enable Function The T6330A features an voltage regulator enable/disable function. To assure the T6330A voltage regulator will switch on, the EN turn on control level must be greater than 1.2V. The T6330A voltage regulator will go into shutdown mode when the voltage on the EN pin falls below 0.4V. The T6330A equips a quick-discharge function to protect the system. When the regulator is turned off by EN pin, the internal MOSFET between VOUT and GND will be turned on to discharge output voltage quickly. If the enable function is not needed in a specific application, it may be tied to GND/VIN to keep the voltage regulator in a continuously on state.

P. 4 Publication Date: JAN. 2008 Revision: A tm TE CH T6330A Thermal Considerations Thermal protection limits power dissipation in T6330A. When the operating junction temperature exceeds 165°C, the OTP circuit starts the thermal shutdown function and turns the pass element off. The pass element turns on again after the junction temperature cools by 30°C. For continuous operation, do not exceed absolute maximum operatiog junction temperature 125°C. The power dissipation definition in device is shown as following formula : PD = (VIN - VOUT) x IOUT + VIN x IQ The maximum power dissipation depends on the thermal resistance of IC package, PCB layout, the rate of surroundings airflow and temperature difference between junction to ambient. The maximum power dissipation can be calculated by following formula : PD(MAX) = ( TJ(MAX) - TA ) / θJA Where TJ(MAX) is the maximum operating junction temperature 125°C, TA is the ambient temperature and the θJA is the junction to ambient thermal resistance. For recommended operating conditions specification of T6330A, where TJ(MAX) is the maximum junction temperature of the die (125°C) and TA is the maximum ambient temperature.
