General Description
The TS5201 series 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 (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.
The TS5201 series 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.
The TS5201 series is available in fixed and adjustable output voltage version in SOP-8 package.
