LM317L

ADJUSTABLE VOLTAGE REGULATOR (POSITIVE) 3-TERMINAL 100mA POSITIVE ADJUSTABLE REGULATOR This monolithic integrated circuit is an adjustable 3-terminal positive voltage regulator designed to supply more than 100mA of load current with an output voltage adjustable over a 1.2 to 37V. It employs internal current limiting, thermal shut-down and safe area compensation. TO-92 PKG (TOP VIEW) 3. VIN 2. VOUT 1.

Co is not needed for stability, however, it does improve transient response. Since lADJ is controlled to less than 100㎂, the error associated with this term is negligible in most applications.
