1 / 6 page UNISONIC TECHNOLOGIES CO., LTD TL431LL Preliminary LINEAR INTEGRATED CIRCUIT www.unisonic.com.tw 1 of 6 Copyright © 2013 Unisonic Technologies Co., Ltd QW-R103-072.a LOW CATHODE CURRENT ADJUSTABLE PRECISION SHUNT REGULATOR DESCRIPTION The UTC TL431LL is an adjustable shunt regulator with three-terminal and thermal stable with full operation range. It features include sharp turn-on characteristics, low output impedance and low temperature coefficient, so Zener diode can be replaced by UTC TL431LL in many applications, for example, charger devices, switching power supply and other adjustable regulators. Any value between VREF (2.5V) and the corresponding maximum cathode voltage (36V) can be set to by UTC TL431LL. The UTC TL431LL is offered in two grade initial voltage tolerance at 25°C, 0.5%, and 1%. FEATURES * High stability under capacitive load * Programmable precise output voltage from 2.5V to 36V * Sink current capacity from 50µA to 100mA * Low minimum cathode current for regulation: 10µA (Typ.), 50µA (Max.) * Low temperature deviation: 4.5mV typical * Low output noise * Wide operating range: -40°C~125°C ORDERING INFORMATION Ordering Number Package Pin Assignment Packing Lead Free Halogen Free 1 2 3 TL431LLK-AE2-R TL431LLG-AE2-R SOT-23-3 K R A Tape Reel Note: Pin Code: K: Cathode R: Reference A: Anode MARKING 4CLL L: Lead Free G: Halogen Free |
