FEATURES  
DESCRIPTION  
•
1.5-A Output Current  
•
Wide-Input Voltage  
The PTN78000 is  
a
series of high-efficiency,  
step-down Integrated Switching Regulators (ISR),  
that represent the third generation in the evolution of  
the popular 78ST100 series of products. In new  
designs it should be considered in place of the  
78ST100, PT78ST100, PT5100, and PT6100 series  
of single in-line pin (SIP) products. The PTN78000 is  
smaller and lighter than its predecessors, and has  
either similar or improved electrical performance  
characteristics. The case-less, double-sided package,  
also exhibits improved thermal characteristics, and is  
compatible with TI's roadmap for RoHS and lead-free  
compliance.

Surface Mount Package Available  
Operating from a wide-input voltage range, the  
PTN78000 provides high-efficiency, step-down  
voltage conversion for loads of up to 1.5 A. The  
output voltage is set using a single external resistor.  
The PTN78000W may be set to any value within the  
range, 2.5 V to 12.6 V, and the PTN78000H from

V to 22 V. The output voltage of the  
PTN78000W can be as little as 2 V lower than the  
input, allowing operation down to 7 V, with an output  
voltage of 5 V. The output voltage of the PTN78000H  
can be as little as 3 V lower than the input, alowing  
operation down to 15 V, with an output voltage of  
12 V.

The PTN78000 has undervoltage lockout and an  
integral on/off inhibit. The modules are suited to a  
wide variety of general-purpose applications that  
operate off 12-V, 24-V, or 28-VDC power.

(B) RSET is required to adjust the output voltage  
higher than 2.5 V for PTN78000W, and high than  
11.824 V for PTN78000H. See the Application  
Information section for specific values.
