FEATURES  
DESCRIPTION  
23  
•
Open Drain Power-On Reset with 200ms Delay  
(TPS775xx)  
The TPS775xx and TPS776xx devices are designed  
to have a fast transient response and be stable with a  
10µF low ESR capacitor. This combination provides  
high performance at a reasonable cost.  
•
•
•
Open Drain Power Good (TPS776xx)  
500mA Low-Dropout Voltage Regulator  
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 85µA  
over the full range of output current, 0mA to 500mA).  
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 1µA at TJ = +25°C.  
Available in Fixed Output and Adjustable  
Versions  
•
Dropout Voltage to 169mV (Typ) at 500mA

•
Ultralow 85µA Typical Quiescent Current  
Fast Transient Response  
2% Tolerance Over Specified Conditions for  
Fixed-Output Versions  
•
•
8-Pin SOIC and 20-Pin TSSOP PowerPAD™  
(PWP) Packages  
Thermal Shutdown Protection  
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.  
APPLICATIONS  
•
FPGA Power  
•
DSP Core and I/O Voltages  
Typical Application Circuit  
(Fixed Voltage Options)  
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  
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.
