Ground 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 w hen the application requires very low dropout voltage. The Chip Enable (EN) includes a C MOS 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 driv er, over temperature shutdown, revered battery protection and a reference bypass pin to improve its already excellent lownoise perfor mance.
