General Description
TS5215 is an efficient linear voltage regulator with ultra low noise output, very low dropout voltage (typically 17mV at light loads and 300mV at 300mA), and very low power consumption (125uA at 100uA), providing high output current even when the application requires very low dropout voltage. The Chip Enable (EN) 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. TS5215 is included a precision voltage reference, error correction circuit, a current limited output driver, over temperature shutdown, revered battery protection and a reference bypass pin to improve its already excellent lownoise performance.
