| 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. ADJ LM317L SOT-89 PKG (FRONT VIEW) FEATURES Output current in Excess of 100mA Output Adjustable Between 1.2V and 37V Internal Thermal-Overload Protection Internal Short-Circuit Current-Limiting Output Transistor Safe-Area Compensation 1.Adj 2. Vout 3. Vin Floating operation for high voltage applications ORDERING INFORMATION Device LM317L LM317F Marking LM317L 317 Package TO-92 SOT-89 BLOCK DIAGRAM HTC 53 ADJUSTABLE VOLTAGE REGULATOR (POSITIVE) LM317L TYPICAL APPLICATIONS Fig.5 Programmable Regulator CI is required when regulator is located in appreciable distance from power supply filter. 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.
