General Description
TS5201 is an efficient linear voltage regulator with ultra low noise output, very low dropout voltage (typically 17mV at
light loads and 165mV at 200mA), and very low power consumption (600uA at 100mA), 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. TS5201 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 low-noise performance.
