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.
