description (continued)
Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 169 mV
at an output current of 500 mA 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, 0 mA to 500 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 1
μ
A at T
J

C.
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 1.5-V, 1.8-V, 2.5-V, 2.8 V (TPS77628 only), and 3.3-V fixed-voltage
versions and in an adjustable version (programmable over the range of 1.5 V to 5.5 V for TPS77501 option and
1.2 V to 5.5 V for TPS77601 option). Output voltage tolerance is specified as a maximum of 2% over line, load,
and temperature ranges. The TPS775xx and TPS776xx families are available in 8 pin SOIC and 20 pin TSSOP
packages.

The TPS77x01 is programmable using an external resistor divider (see application information). The D and PWP
packages are available taped and reeled. Add an R suffix to the device type (e.g., TPS77501DR).
The TPS775xx has an open-drain power-on reset with a 200-ms delay function. The TPS776xx has an open-drain
power good function.
