 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 V_REF (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
