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.

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.

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.

APPLICATIONS INFORMATION
Basic Circuit Operation
External Capacitors
The LM317M is a three−terminal floating regulator. In
operation, the LM317M develops and maintains a nominal

output voltage is given by:
ripple from being amplified as the output voltage is
increased. A 10 mF capacitor should improve ripple
rejection about 15 dB at 120 Hz in a 10 V application.
Although the LM317M is stable with no output

external capacitance can cause excessive ringing. An output

this, all quiescent operating current is returned to the output
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
