description
The TPS71Hxx integrated circuits are a family of
micropower low-dropout (LDO) voltage regula-
tors. 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 TPS71H50) 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
