General Description
TS5213 is an efficient linear voltage regulator with ultra low noise output, very low dropout voltage (typically 20mV at
light loads and 300mV at 80mA), and very low ground current (225uA at 20mA), 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. TS5213 is included a precision voltage reference, error correction circuit, a current limited output driver, over
temperature shutdown and revered battery protection.

... The TS5213 series requires an output capacitor to maintain stability and improve transient response is necessary. The TS5213 is ultra stable, requiring only 0.47uF of output capacitance for stability stable with all type of capacitors, including the tiny, low-ESR ceramic chip capacitors. The output capacitor value may be increased without limit ...
