TS9012

T S9 0 1 2 300mA Low Quiescent Current CMOS LDO with Enable Function SOT-25 Pin Definition: 1. Ground 2. Input 3. Enable 4. N/C 5. Output General Description TS9012 series is combine high accuracy with very low pow er consumption, providing high output current even when the application requires very low dropout voltage. The Chip Enable (C E) includes a C MOS 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 dr iver and over temperature shutdown. Features ● ● ● ● ● ● ● ● ● ● ● Dropout voltage typically 0.4V @ Io=300mA ( Vo=5V) Output current up to 300mA Low pow er consumption 10uA (Typ.)

Exceeding the absolute maximum rating may damage the device. 2. The device is not guaranteed to func tion 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 w ill result in excessive die temperature, and the regulator w ill go into ther mal shutdown. 4. Output voltage temperature coefficient is defined as the wors t case voltage change divided by the total temperature r ange. 5. Regulation is measured at cons tant junction temperatur e using low duty cycle pulse testing. Parts are tested for load regulation in the load r ange from 1mA to 150mA( VOUT >2.5V) and 1mA to 80mA( VOUT
