SBVS184 –DECEMBER 2011  
28-V Input Voltage, 50-mA Voltage Regulator  
Check for Samples: TPS7A42  
1
FEATURES  
DESCRIPTION  
The TPS7A42 is a very high voltage-tolerant linear  
23  
•
Wide Input Voltage Range: 7 V to 28 V  
Accuracy:  
regulator that offers the benefits of  
a
•
thermally-enhanced package (MSOP-8), and is able  
to withstand continuous dc or transient input voltages  
of up to 28 V.  
–
–
Nominal: 1%  
Over Line, Load, and Temperature: 2.5%  
•
•
•
•
•
•
Low Quiescent Current: 25 µA  
The TPS7A42 is stable with any output capacitance  
greater than 4.7 µF and any input capacitance  
greater than 1 µF (over temperature and tolerance).  
Therefore, implementations of this device require  
minimal board space because of its miniaturized  
packaging (MSOP-8) and a potentially small output  
capacitor. In addition, the TPS7A42 offers an enable  
pin (EN) compatible with standard CMOS logic to  
enable a low-current shutdown mode.  
Quiescent Current at Shutdown: 4.1 µA  
Maximum Output Current: 50 mA  
CMOS Logic-Level-Compatible Enable Pin  
Adjustable Output Voltage: ~1.175 V to 26 V  
Stable with Ceramic Capacitors:  
–
–
Input Capacitance: ≥ 1 µF  
Output Capacitance: ≥ 4.7 µF  
The TPS7A42 has an internal thermal shutdown and  
current limiting to protect the system during fault  
conditions. The MSOP-8 packages has an operating  
temperature range of TJ = –40°C to +125°C.  
•
•
Dropout Voltage: 290 mV  
Built-In Current-Limit and Thermal Shutdown  
Protection  
In addition, the TPS7A42 is ideal for generating a  
low-voltage supply from intermediate voltage rails in  
telecom and industrial applications; not only it can  
supply a well-regulated voltage rail, but it can also  
withstand and maintain regulation during fast voltage  
transients. These features translate to simpler and  
more cost-effective electrical surge-protection circuitry  
for a wide range of applications.
