General Description
The TS9009 series is combine high accuracy with very low power consumption (225uA at 20mA output), and very low
dropout voltage (from typically 20mV at light loads to 300mV at 80mA).
The TS9009 series is designed for optimal performance with low-value, low cost ceramic capacitors. In most applications
only 0.47uF of output capacitance is required for stability, and specifically for battery power devices. The Chip Enable
(CE) includes a CMOS or TTL compatible input allows the output to be turned off to prolong battery life. When it is
shutdown, power consumption drops practically to zero. If Chip Enable control is not required, the Enable pin can be tied
to the input for 3-terminal operation. The TS9009 series is included a precision voltage reference, current limiting, over
temperature shutdown, and protection against reversed battery connection.
This series are offered in 5-pin SOT-25 package.
