FEATURES

DESCRIPTION

The LM117HV are adjustable 3-terminal positive

• Available with Radiation Ensured

voltage regulators capable of supplying either 0.5A or

– Total Ionizing Dose 100 krad(Si)

1.5A over a 1.2V to 57V output range. They are

– Low Dose Rate Qualified 100 krad(Si)

exceptionally easy to use and require only two

external resistors to set the output voltage. Further,

• Adjustable Output down to 1.2V

both line and load regulation are better than standard

• Specified 0.5A or 1.5A Output Current

fixed regulators.

• Line Regulation Typically 0.01%/V

In addition to higher performance than fixed

• Load Regulation Typically 0.1%

regulators, the LM117HV series offers full overload

• Current Limit Constant with Temperature

protection available only in IC's. Included on the chip

are current limit, thermal overload protection and safe

• Eliminates the Need to Stock Many Voltages

area protection. All overload protection circuitry

• 80 dB Ripple Rejection

remains fully functional even if the adjustment

• Output is Short-Circuit Protected

terminal is disconnected.

Normally, no capacitors are needed unless the device

is situated 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.

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 voltage, supplies of several

hundred volts can be regulated as long as the

maximum input to output differential is not exceeded,

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

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. Supplies with electronic

shutdown can be achieved by clamping the

adjustment terminal to ground which programs the

output to 1.2V where most loads draw little current.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is functional, but do not ensure specific performance limits. For ensured specifications and test conditions, see the

Electrical Characteristics. The ensured specifications apply only for the test conditions listed. Some performance characteristics may

degrade when the device is not operated under the listed test conditions.

(2) The maximum power dissipation must be derated at elevated temperatures and is dictated by T

Jmax

(maximum junction temperature),

(package junction to ambient thermal resistance), and T

(ambient temperature). The maximum allowable power dissipation at any

temperature is P

Dmax

= (T

Jmax

- T

) / θ

or the number given in the Absolute Maximum Ratings, whichever is lower. "Although power

dissipation is internally limited, these specifications are applicable for power dissipations of 2W for the PFM package and 20W for the

TO package."

(3) The package material for these devices allows much improved heat transfer over our standard ceramic packages. In order to take full

advantage of this improved heat transfer, heat sinking must be provided between the package base (directly beneath the die), and either

metal traces on, or thermal vias through, the printed circuit board. Without this additional heat sinking, device power dissipation must be

calculated using θ

, rather than θ

, thermal resistance. It must not be assumed that the device leads will provide substantial heat

transfer out the package, since the thermal resistance of the lead frame material is very poor, relative to the material of the package

base. The stated θ

thermal resistance is for the package material only, and does not account for the additional thermal resistance

between the package base and the printed circuit board. The user must determine the value of the additional thermal resistance and

must combine this with the stated value for the package, to calculate the total allowed power dissipation for the device.
