Since a PNP power transistor is used, dropout voltage is very low, making it possible to maintain stable output voltage even as the battery decreases. This allows longer battery life. The TK712xx has a noise bypass pin available for noise reduction. The TK712xx is available in a miniature SOT-25 surface mount package. 20 P TK712xx NOISE BYPASS GND VOUT ORDERING INFORMATION TK712 Voltage Code Tape/Reel Code BLOCK DIAGRAM VOUT VOLTAGE CODE 20 = 2.0 V 25 = 2.5 V 28 = 2.8 V 30 = 3.0 V 33 = 3.3 V 35 = 3.5 V 40 = 4.0 V 45 = 4.5 V 50 = 5.0 V TAPE/REEL CODE TL: Tape Left NOISE BYPASS THERMAL PROTECTION BANDGAP REFERENCE GND January 1999 TOKO, Inc.
