LM317M  
500 mA Adjustable Output,  
Positive Voltage Regulator  
The LM317M is an adjustable three−terminal positive voltage  
regulator capable of supplying in excess of 500 mA over an output  
voltage range of 1.2 V to 37 V. This voltage regulator is exceptionally  
easy to use and requires only two external resistors to set the output  
voltage. Further, it employs internal current limiting, thermal  
shutdown and safe area compensation, making it essentially blow−out  
proof.

Heatsink surface  
connected to Pin 2  
The LM317M serves a wide variety of applications including local,  
on−card regulation. This device also makes an especially simple  
adjustable switching regulator, a programmable output regulator, or by  
connecting a fixed resistor between the adjustment and output, the  
LM317M can be used as a precision current regulator.

DEVICE MARKING INFORMATION  
See general marking information in the device marking  
section on page 13 of this data sheet.  
Since I is controlled to less than 100 mA, the error associated with this  
Adj  
term is negligible in most applications.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit  
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,  
damage may occur and reliability may be affected.

terminal. This imposes the requirement for a minimum load  
current. If the load current is less than this minimum, the  
output voltage will rise.  
Since the LM317M is a floating regulator, it is only the  
voltage differential across the circuit which is important to  
performance, and operation at high voltages with respect to  
ground is possible.  
Protection Diodes  
When external capacitors are used with any IC regulator  
it is sometimes necessary to add protection diodes to prevent  
the capacitors from discharging through low current points  
into the regulator.  
Figure 20 shows the LM317M with the recommended  
protection diodes for output voltages in excess of 25 V or  
high capacitance values (C > 25 mF, C > 5.0 mF). Diode

The LM317M is capable of providing extremely good  
load regulation, but a few precautions are needed to obtain  
maximum performance. For best performance, the
