DESCRIPTION
2 Qualified for Automotive Applications
The TPS782xx family of low-dropout regulators
• Low IQ: 1 μA
• 150-mA Low-Dropout Regulator
• Low Dropout at 25°C: 130 mV at 150 mA
• Low Dropout at 85°C: 175 mV at 150 mA
• 4% Accuracy Over Load/Line/Temperature
• Available in Fixed Voltage Options (2.5 V,
2.7 V, 2.8 V, and 3 V) Using Innovative Factory
(LDOs) offers the benefits of ultra-low power
(IQ = 1 μA), and miniaturized packaging (2-mm×2-mm
SON).
This LDO is designed specifically for battery-powered
applications where ultra-low quiescent current is a
critical parameter. The TPS782, with ultra-low IQ
(1 μA), is ideal for microprocessors, memory cards,
and smoke detectors.
EEPROM Programming
The ultra-low power and miniaturized packaging allow
• Stable with a 1-μF Ceramic Capacitor
designers to customize power consumption for
• Thermal Shutdown and Overcurrent Protection
• CMOS Logic Level Compatible Enable Pin
specific applications. Consult with your local factory
representative for exact voltage options and ordering
information; minimum order quantities may apply.
• Available in DDC (TSOT23-5) or DRV (2-mm x
2-mm SON-6) Packages
The TPS782xx family is designed to be compatible
with the TI MSP430 and other similar products. The
APPLICATIONS

enable pin (EN) is compatible with standard CMOS
logic. This LDO is stable with any output capacitor
greater than 1.0 μF. Therefore, this device requires

minimal board space because of miniaturized
packaging and a potentially small output capacitor.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
