LM117HV/LM317HV

3-Terminal Adjustable Regulator

Also, it makes an especially simple adjustable switching

regulator, a programmable output regulator, or by connecting

a fixed resistor between the adjustment and output, the

LM117HV can be used as a precision current regulator. Sup-

plies with electronic shutdown can be achieved by clamping

the adjustment terminal to ground which programs the out-

put to 1.2V where most loads draw little current.

General Description

The LM117HV/LM317HV are adjustable 3-terminal positive

voltage regulators capable of supplying in excess of 1.5A

over a 1.2V to 57V output range. They are exceptionally

easy to use and require only two external resistors to set the

output voltage. Further, both line and load regulation are bet-

ter than standard fixed regulators. Also, the LM117HV is

packaged in standard transistor packages which are easily

mounted and handled.

The LM117HVK STEEL and LM317HVK STEEL are pack-

aged in standard TO-3 transistor packages, while the

LM117HVH and LM317HVH are packaged in a solid Kovar

base TO-39 transistor package. The LM317HVT uses a TO-

220 plastic package. The LM117HV is rated for operation

from −55˚C to +150˚C, and the LM317HV from 0˚C to

+125˚C.

In addition to higher performance than fixed regulators, the

LM117HV series offers full overload protection available only

in IC’s. Included on the chip are current limit, thermal over-

load protection and safe area protection. All overload protec-

tion circuitry remains fully functional even if the adjustment

terminal is disconnected.

Features

Normally, no capacitors are needed unless the device is situ-

ated more than 6 inches from the input filter capacitors in

which case an input bypass is needed. An optional output

capacitor can be added to improve transient response. The

adjustment terminal can be bypassed to achieve very high

ripple rejections ratios which are difficult to achieve with

standard 3-terminal regulators.

n Adjustable output down to 1.2V

n Guaranteed 1.5A output current

n Line regulation typically 0.01%/V

n Load regulation typically 0.1%

n Current limit constant with temperature

n 100% electrical burn-in

Besides replacing fixed regulators, the LM117HV is useful in

a wide variety of other applications. Since the regulator is

“floating” and sees only the input-to-output differential volt-

age, supplies of several hundred volts can be regulated as

long as the maximum input to output differential is not ex-

ceeded, i.e. do not short the output to ground.

n Eliminates the need to stock many voltages

n Standard 3-lead transistor package

n 80 dB ripple rejection

n Output is short-circuit protected

n P⁺Product Enhancement tested

Typical Applications

1.2V-45V Adjustable Regulator

DS009062-1

Full output current not available at high input-output voltages

†

Optional — improves transient response. Output capacitors in the range of 1 µF to 1000 µF of aluminum or tantalum electrolytic

are commonly used to provide improved output impedance and rejection of transients.

*Needed if device is more than 6 inches from filter capacitors.
