description
The TPS779xx is a low-dropout regulator with
integrated power-on reset. The device is capable
of supplying 250 mA of output current with a
dropout of 200 mV (TPS77930). Quiescent
current is 92 A at full load dropping down to 1 A
when the device is disabled. The device is
optimized to be stable with a wide range of output
capacitors including low ESR ceramic (10 F) or
low capacitance (1 F) tantalum capacitors. The
device has extremely low noise output performance (55 V
TPS779xx is designed to have a fast transient response for larger load current changes.
The TPS779xx is offered in 1.8-V, 2.5-V, and 3-V fixed-voltage versions and in an adjustable version
(programmable over the range of 1.5 V to 5.5 V). Output voltage tolerance is 2% over line, load, and temperature
ranges. The TPS779xx family is available in 8-pin MSOP (DGK) packages.
Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 200 mV
at an output current of 250 mA for 3.3 volt option) 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 92 A over the full range of output current, 0 mA to 250 mA). These two key
specifications yield a significant improvement in operating life for battery-powered systems.
The device is enabled when the EN pin is connected to a high-level input voltage. This LDO family also features
a sleep mode; applying a TTL low signal to EN (enable) shuts down the regulator, reducing the quiescent current
to less than 1 A at T
= 25 C.
