| TS9010 150mA CMOS Low Dropout Voltage Regulator with Enable Pin assignment 1. Ground 2. Input 3. Enable 4. N/C 5. Output Low Power Consumption Low Drop Out Voltage 0.4V Enable Shutdown General Description The TS9010 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 TS9010 series is included a precision voltage reference, error correction circuit, a current limited output driver and over temperature shutdown. This series are offered in 5-pin SOT-25 package. Features Dropout voltage typically 0.4V @Io=150mA (Vo=5V) Output current up to 150mA (Vout=3V) Low power consumption Output voltage +/-2% Internal current limit Thermal shutdown protection Ordering Information Part No. Operating Temp.

C Electrical Characteristics (continued) Note 1: Exceeding the absolute maximum rating may damage the device. Note 2: The device is not guaranteed to function outside its operating rating. Note 3: The maximum allowable power dissipation at any Ta is Pd(max) = [ Tj(max) - Ta] * ja. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. Note 4: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range. Note 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. Note 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. Note 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. Note 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. Application Examples Standard Circuit Typical Application Circuit 2 TS9010 series 3-4 2004/09 rev.
