description
The TPS71xx integrated circuits are a family
of micropower low-dropout (LDO) voltage
regulators. An order of magnitude reduction in
dropout voltage and quiescent current over
conventional LDO performance is achieved by
replacing the typical pnp pass transistor with a
PMOS device.
Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (maximum of 32
mV at an output current of 100 mA for the TPS7150) and is directly proportional to the output current (see
Figure 1). Additionally, since the PMOS pass element is a voltage-driven device, the quiescent current is very
low and remains independent of output loading (typically 285
μ
A over the full range of output current, 0 mA to
500 mA). These two key specifications yield a significant improvement in operating life for battery-powered
systems. The LDO family also features a sleep mode; applying a TTL high signal to EN (enable) shuts down
the regulator, reducing the quiescent current to 0.5
