For LLP devices, both V IN pins must be tied together for full current operation (250mA maximum per pin). GND Circuit ground for the regulator. This is connected to the die through the lead frame, and also functions as the heat sink when the large ground pad is soldered down to a copper plane. SNS Output sense pin allows remote sensing at the load which will eliminate the error in output voltage due to voltage drops caused by the resistance in the traces between the regulator and the load. This pin must be tied to V OUT. V EN The enable pin allows the part to be turned ON and OFF by pulling this pin high or low. V OUT Regulated output voltage Ordering Information Order Number Package Marking Package Type Package Drawing Supplied As LP38691SD-1.8 L118B 6-Lead LLP SDE06A 1000 Units Tape and Reel LP38691SD-2.5 L119B 6-Lead LLP SDE06A 1000 Units Tape and Reel LP38691SD-3.3 L120B 6-Lead LLP SDE06A 1000 Units Tape and Reel LP38691SD-5.0 L121B 6-Lead LLP SDE06A 1000 Units Tape and Reel LP38691DT-1.8 LP38691DT-1.8 TO-252 TD03B Available Soon LP38691DT-2.5 LP38691DT-2.5 TO-252 TD03B Available Soon LP38691DT-3.3 LP38691DT-3.3 TO-252 TD03B Available Soon LP38691DT-5.0 LP38691DT-5.0 TO-252 TD03B Available Soon LP38693SD-1.8 L128B 6-Lead LLP SDE06A 1000 Units Tape and Reel LP38693SD-2.5 L129B 6-Lead LLP SDE06A 1000 Units Tape and Reel LP38693SD-3.3 L130B 6-Lead LLP SDE06A 1000 Units Tape and Reel LP38693SD-5.0 L131B 6-Lead LLP SDE06A 1000 Units Tape and Reel LP38693MP-1.8 LJVB SOT-223 MP05A 1000 Units Tape and Reel www.national.com 2 |
