The TS5205 series is an efficient linear voltage regulator with ultra low noise output, very low dropout voltage (typically 17mV at light loads and 165mV at 150mA), and very low power consumption (600uA at 100mA), providing high output current even when the application requires very low dropout voltage. The Chip Enable (CE) includes a CMOS or TTL compatible input allows the output to be turned off to prolong battery life. When shutdown, power consumption drops nearly to zero.
