General Description

The EM317L is an adjustable 3-terminal positive voltage regulator capable of supplying 100mA 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.
EM317L offers full overload protection.
Included on the chip current limit, thermal overload protection, and safe-area protection.
Normally, no capacitors is needed unless the device is situated far from the input filter capacitors in which case an input bypass is needed.
An optional output capacitor can added to improve transient response.
