TS5205 Taiwan Semiconductor 150mA Low Noise LDO Voltage Regulator with Enable Function GENERAL DESCRIPTION FEATURES Ultra Low Noise Output TS5205 is an efficient linear voltage regulator with ultra- Output Current up to 150mA low noise output, very low dropout voltage (typically Low Dropout Voltage 17mV at light loads and 165mV at 150mA), and very low Low Power Consumption power consumption (600A at 100mA), providing high Zero Off-mode Current output current even when the application requires very Logic Controlled Electronic Enable low dropout voltage. The Chip Enable (EN) includes a Internal Current Limit CMOS or TTL compatible input allows the output to be Thermal Shutdown Protection turned off to prolong battery life. When shutdown, power consumption drops nearly to zero. TS5205 is included a APPLICATION precision voltage reference, error correction circuit, a Cellular Telephones current limited output driver, over temperature Palmtops, Notebook Computers Battery Powered Equipment shutdown, revered battery protection and a reference Consumer and Personal Electronics bypass pin to improve its already excellent low-noise SMPS Post Regulator and DC to DC Modules performance.
