Wide Input Voltage Range: 2.5V to 10V  
Low Quiescent Current: 3.2μA at 80mA  
Stable with any Capacitor > 0.47μF  
Output Current: 80mA  
offer the benefits of wide input voltage range,  
low-dropout voltage, low-power operation, and  
miniaturized packaging. These devices, which  
operate over an input range of 2.5V to 10V, are  
stable with any capacitor ≥ 0.47μF. The 2.5V to 10V  
input voltage range, combined with 3.2μA quiescent  
current, makes this device particularly well-suited for  
two-cell alkaline, and two-cell lithium, and other low  
quiescent current sensitive battery applications. The  
low dropout voltage and low quiescent current allow  
operation at extremely low power levels. Therefore,  
the devices are ideal for power battery management  
ICs. Specifically, because the device is enabled as  
soon as the applied voltage reaches the minimum  
input voltage, the output is quickly available to power  
continuously-operating, battery-charging ICs.  
Dropout Voltage: 415mV at 50mA Load  
Available in Fixed 3.3V or Adjustable (1.2V to  
8.8V) Versions

TPS715xx  
APPLICATIONS  
The typical PNP pass transistor has been replaced by  
a PMOS pass element. Because the PMOS pass  
element behaves as a low-value resistor, the low  
dropout voltage (typically 415mV at 50mA of load  
current) is directly proportional to the load current.  
The quiescent current (3.2μA, typical) is stable over  
the entire range of the output load current (0mA to  
80mA).

Ultralow-Power Microcontrollers  
Industrial/Automotive Applications  
PDAs  
Portable, Battery-Powered Equipment  
The TPS714xx is available in a 2mm x 2mm SON-6  
package ideal for high power dissipation, or an  
SC70-5 package ideal for handheld and ultra-portable  
applications.
