description

The TPS789xx family of low-dropout (LDO)
voltage regulators offers the benefits of
low-dropout voltage, ultralow-power operation,
low-output noise, and miniaturized packaging.
These regulators feature low-dropout voltages
and ultralow quiescent current compared to
conventional LDO regulators. An internal resistor,
in conjunction with an external bypass capacitor,
creates a low-pass filter to reduce the noise. The
TPS78930 exhibits only 56 μV RMS of output
voltage noise using 0.01 μF bypass and 10 μF
output capacitors. Offered in a 5-terminal small
outline integrated-circuit SOT-23 package, the
TPS789xx series devices are ideal for
micropower operations, low output noise, and
where board space is limited.
The usual PNP pass transistor has been replaced
by a PMOS pass element. Because the PMOS
pass element behaves as a low-value resistor, the
dropout voltage is very low, typically 115 mV at
100 mA of load current (TPS78930), and is
directly proportional to the load current. The
quiescent current is ultralow (17 μA typically) and
is stable over the entire range of output load
current (0 mA to 100 mA). Intended for use in
portable systems such as laptops and cellular
phones, the ultralow-dropout voltage feature and
ultralow-power operation result in a significant
increase in system battery operating life.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
