TS5204 Taiwan Semiconductor 80mA Low Noise Ultra Low Dropout Voltage Regulator DESCRIPTION FEATURES The TS5204 series is an efficient linear voltage Ultra-Low Noise Output regulator with ultra-low noise output, very low dropout Output Current up to 80mA voltage (typically 20mV at light loads and 300mV at Low Dropout Voltage 80mA), and very low power consumption (500A at Low Power Consumption 50mA), providing high output current even when the Internal Current Limit application requires very low dropout voltage. Thermal Shutdown Protection The TS5204 series includes a precision voltage RoHS Compliant reference, current limit, over temperature shutdown and Halogen-free according to IEC 61249-2-21 revered battery protection.

Exceeding the absolute maximum rating may damage the device. 2. The maximum allowable power dissipation at any TA is PD(MAX) = TJ(MAX) - Ta + RJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.

The device is not guaranteed to function outside its operating rating. 4. Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range. 5. 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. 6. 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. 7. 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. 8. 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 80mA load pulse at V =16V for t=10ms. IN 2 Version: M2003
