General Description
TS9012 series is combine high accuracy with very low power consumption, 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. The TS9012 series is included a precision voltage reference,
error correction circuit, a current limited output driver and over temperature shutdown.

Notes:
1. Exceeding the absolute maximum rating may damage the device.
2. The device is not guaranteed to function outside its operating rating.
3. The maximum allowable power dissipation at any Ta is Pd(max) = [ TJ(max) - Ta] * Өja. Exceeding the maximum
allow able power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.
4. Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature
range.
5. Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load
regulation in the load range from 1mA to 150mA(VOUT >2.5V) and 1mA to 80mA(VOUT <2.5V). Changes in output
voltage due to heating effects are covered by the thermal regulation specification.
6. Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal
value measured at 1V differential.
7. Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from
the supply is the sum of the load current plus the ground pin current.
8. Thermal regulation is defined as the change in output voltage at a time “t” after a change in power dissipation is
applied, excluding load or line regulation effects. Specifications are for a 150mA load pulse at VIN =12V for t=10mS.
