description
This device is designed to have an ultra-low quiescent current and be stable with a 4.7-
μ
F capacitor. This
combination provides high performance at a reasonable cost.
Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 85 mV
at an output current of 150 mA for the TPS76550) and is directly proportional to the output current. Additionally,
since the PMOS pass element is a voltage-driven device, the quiescent current is very low and independent
of output loading (typically 35
μ
A over the full range of output current, 0 mA to 150 mA). These two key
specifications yield a significant improvement in operating life for battery-powered systems. This LDO family
also features a sleep mode; applying a TTL high signal to EN (enable) shuts down the regulator, reducing the
quiescent current to less than 1
μ
A (typ).
