description
The TPS760xx is a 50mA, low dropout (LDO) voltage regulator designed specifically for battery-powered
applications. A proprietary BiCMOS fabrication process allows the TPS760xx to provide outstanding
performance in all specifications critical to battery-powered operation.
The TPS760xx is available in a space-saving SOT–23 package and operates over a junction temperature range
of –40°C to 125°C.

Figure 17. TPS760xx Typical Application
over current protection
The over current protection circuit forces the TPS760xx into a constant current output mode when the load is
excessive or the output is shorted to ground. Normal operation resumes when the fault condition is removed.
An overload or short circuit may also activate the over temperature protection if the fault condition persists.
over temperature protection
The thermal protection system shuts the TPS760xx down when the junction temperature exceeds 160_C. The
device recovers and operates normally when the temperature drops below 150_C.
input capacitor
A 0.047 µF or larger ceramic decoupling capacitor with short leads connected between IN and GND is
recommended. The decoupling capacitor may be omitted if there is a 1 µF or larger electrolytic capacitor
connected between IN and GND and located reasonably close to the TPS760xx. However, the small ceramic
device is desirable even when the larger capacitor is present, if there is a lot of high frequency noise present
in the system.
output capacitor
Like all low dropout regulators, the TPS760xx requires an output capacitor connected between OUT and GND
to stabilize the internal control loop. The minimum recommended capacitance value is 2.2 µF and the ESR
(equivalent series resistance) must be between 0.1 Ω and 20 Ω. Capacitor values of 2.5-µF or larger are
acceptable, provided the ESR is less than 20 Ω. Solid tantalum electrolytic, aluminum electrolytic, and multilayer
ceramic capacitors are all suitable, provided they meet the requirements described above. Most of the
commercially available 2.2-µF surface-mount solid-tantalum capacitors, including devices from Sprague,
Kemet, and Nichicon, meet the ESR requirements stated above. Multilayer ceramic capacitors should have
minimum values of 2.5 µF over the full operating temperature range of the equipment.
enable (EN)
A logic zero on the enable input shuts the TPS760xx off and reduces the supply current to less than 1 µA. Pulling
the enable input high causes normal operation to resume. If the enable feature is not used, EN should be
connected to IN to keep the regulator on all of the time. The EN input must not be left floating.

APPLICATION INFORMATION
reverse current path
The power transistor used in the TPS760xx has an inherent diode connected between IN and OUT as shown
in the functional block diagram. This diode conducts current from the OUT terminal to the IN terminal whenever
IN is lower than OUT by a diode drop. This condition does not damage the TPS760xx, provided the current is
limited to 100mA.
