2 / 16 page Philips Semiconductors Product specification TL431C, TL431AC, TL431I, TL431AI, LM431AC Adjustable precision shunt regulators 2 1997 Feb 25 853–1927 17795 DESCRIPTION The TL431 and TL431A are 3-terminal adjustable shunt regulators with specified thermal stability over applicable automotive and commercial temperature ranges. The output voltage may be set to any value between VREF (approximately 2.5V) and 36V with two external resistors (see Figure 4). These devices have a typical output impedance of 0.2 Ω. Active output circuitry provides a very sharp turn-on characteristic, making these devices excellent replacements for zener diodes in many applications like on-board regulation, adjustable power supplies and switching power supplies. The TL431C and TL431AC are characterized for operation from 0 °C to +70°C; the TL431I and TL431AI are characterized for operation from –40 °C to +85°C. FEATURES • Equivalent full-range temperature coefficient: 30ppm/°C • 0.2Ω typical output impedance • Sink current capability: 1mA to 100mA • Low output noise • Adjustable output voltage: V REF to 36V PIN CONFIGURATIONS 1 2 3 45 6 7 8 CATHODE ANODE ANODE NC REF ANODE ANODE NC CATHODE ANODE REF M, D Package SOT96-1 1 2 3 45 6 7 8 CATHODE NC NC NC REF NC ANODE NC N, P Package SOT97-1 Z, LP, U Package SOT54 SL01167 TOP VIEW TOP VIEW Figure 1.
