description (continued)
Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 115 mV
at an output current of 150 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
µA 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.
The device is enabled when the EN pin is connected to a low-level input voltage. 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
µA at TJ = 25°C.
The TPS771xx features an integrated power-on reset, commonly used as a supply voltage supervisor (SVS)
or reset output voltage. The RESET output of the TPS771xx initiates a reset in DSP, microcomputer or
microprocessor systems at power-up and in the event of an undervoltage condition. An internal comparator in
the TPS771xx monitors the output voltage of the regulator to detect an undervoltage condition on the regulated
output voltage. When OUT reaches 95% of its regulated voltage, RESET will go to a high-impedance state after
a 220 ms delay. RESET will go to low-impedance state when OUT is pulled below 95% (i.e. over load condition)
of its regulated voltage.
For the TPS772xx, the power good terminal (PG) is an active high output, which can be used to implement a
power-on reset or a low-battery indicator. An internal comparator in the TPS772xx monitors the output voltage
of the regulator to detect an undervoltage condition on the regulated output voltage. When OUT falls below 82%
of its regulated voltage, PG will go to a low-impedance state. PG will go to a high-impedance state when OUT
is above 82% of its regulated voltage.

The TPS77101 and TPS77201 are programmable using an external resistor divider
(see application information). The DGK package is available taped and reeled. Add
an R suffix to the device type (e.g., TPS77101DGKR).
