FAST-TRANSIENT-RESPONSE 500mA LOW-DROPOUT VOLTAGE REGULATORS
This
combination
Because the PMOS device behaves as a low-value
resistor, the dropout voltage is very low (typically
169mV at an output current of 500mA for the
TPS77x33) 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
85
μ
A over the full range of output current, 0mA to
500mA).

features a sleep mode; applying a TTL high signal to

The RESET output of the TPS775xx initiates a reset
in microcomputer and microprocessor systems in the
event of an undervoltage condition. An internal
comparator in the TPS775xx monitors the output
voltage of the regulator to detect an undervoltage
condition on the regulated output voltage.

Power good (PG) of the TPS776xx is an active high
output, which can be used to implement a power-on
reset or a low-battery indicator.
The TPS775xx and TPS776xx are offered in 1.5V,
1.6V (TPS77516 only), 1.8V, 2.5V, 2.8V (TPS77628
only), and 3.3V fixed-voltage versions and in an
adjustable version (programmable over the range of
1.5V to 5.5V for the TPS77501 and 1.2V to 5.5V for
the TPS77601). Output voltage tolerance is specified
