The T6330A performance is optim ized for battery- powered systems to deliver ultra low noise and low quiescent current. Regulator ground current increases only slightly in dropout, further prolonging the battery life. The T6330A also works with sm all output capacitor, reducing the am ount of board space necessary f or power applications, critical in hand-held wireless devices. The T6330A consumes less than 0.01uA in shutdown m ode and has fast turn-on tim e less than 50us. The other features include ultra low dropout voltage, high output accuracy, current lim iting protection, and high ripple rejection ratio. Available in the SOT-223 , TO-252 and TO - 263 packages.

Revision: A Applications Information Like any voltage regulator, the external capacitors used for the T6330A must be carefully selected for regulator stability and performance. Using a capacitor whose value is > 10uF on the T6330A input and the amount of capacitance can be increas ed 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 line- transient 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 perfor mance consideration. Using a ceramic capacitor whose value is at least 10uF with ESR is more than 20m Ω 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 redu ce noise and improve load transient response, stability and PSRR.The output capacitor should be lo cated 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 f unction is not needed in a specific application, it may be tied to GND/VIN to keep the voltage regulator in a continuously on state.

Revision: A Thermal Considerations Thermal protection limits power dissipation in T6330A. When the operating junction temperature exceeds 165°C, the OTP circuit starts the thermal shutdow n 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.
