DESCRIPTION
The TPS714xx low-dropout (LDO) voltage regulators
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.
The typical PNP pass transistor has been replaced by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).
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.
