3 / 8 page TS5213 80mA Low Noise LDO Voltage Regulator with Enable Function 3/8 Version: B07 Electrical Specification (Continue) Note 1: Exceeding the absolute maximum rating may damage the device. Note 2: The maximum allowable power dissipation at any Ta is Pd(max) = [TJ(MAX) - Ta] + ӨJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. Note 3: Devices are ESD sensitive. Handling precautions recommended. Note 4: The device is not guaranteed to function outside its operating rating. Note 5: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range. Note 6: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load regulation in the load range from 1mA to 80mA. Changes in output voltage due to heating effects are covered by the thermal regulation specification. Note 7: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at 1V differential. Note 8: Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from the supply is the sum of the load current plus the ground pin current. Note 9: Thermal regulation is defined as the change in output voltage at a time “t” after a change in power dissipation is applied, excluding load or line regulation effects. Specifications are for a 80mA load pulse at VIH =16V for t=10mS. Application Information Enable Input TS5213 series feature an active-high (>2V) enable (EN) input that allows ON/OFF control of the regulator. Current drain reduces to “zero” when the device is shutdown, with only micro-amperes of leakage current. The EN is compatible with CMOS logic interfacing. EN may be directly tied to VIH and pulled up to the maximum supply voltage. Input Capacitor Requirement An input capacitor of 0.17uF or greater is recommended when the device is more than 10” away from the bulk AC supply capacitance or when the supply is a battery. Output Capacitor Requirement The TS5213 series requires an output capacitor to maintain stability and improve transient response is necessary. The TS5213 is ultra stable, requiring only 0.47uF of output capacitance for stability. It is stable with all type of capacitors, including the tiny, low-ESR ceramic chip capacitors. The output capacitor value may be increased without limit. No Load Stability The TS5213 series will remain stable and in regulation with no load, unlike many other voltage regulators. This is especially important in CMOS RAM keep alive applications. Fixed Output Regulator Application Low Noise Fixed Voltage Application TS5213 series is offered a smaller system solution, it is only required a small multilayer ceramic capacitor for stability.
