General Description

The TS317L is adjustable 3-terminal positive voltage regulator capable of supplying in excess of 100mA over an output

voltage range of 1.25 V to 37 V. This voltage regulator is exceptionally easy to use and require 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.

Besides replacing fixed regulators, the TS317L 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.

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 TS317L can be used as a precision current regulator. Supplyies

with electronic shutdown can be achieved by clamping the adjustment terminal to ground which programs the output to

1.25V where most loads draw little current.

The TS317L is offered in 3-pin TO-92 and SOP-8 package.

Features

Standard Application

ꢀ

Output current up to 100mA

Output Adjustable between 1.25 V and 37 V

Internal Thermal Overload Protection

Internal Short-Circuit Current Limiting Constant with

Temperature

ꢀ

Output Transistor Safe-Area Compensation

Floating Operation for High Voltage Applications

Eliminates Stocking Many Fixed Voltages

Output voltage offered in 4% tolerance

Vout = 1.25 V * (1 + R2 / R1 ) + Iadj_j* R2

Since I_Adjis controlled to less than 100 µA, the error

associated with this term is negligible in most applications

A common ground is required between the input and the

output voltages. The input voltage must remain typically

2.0V above the output voltage even during the low point

on the Input ripple voltage.
