BM432

BOOKLY MICRO LOW VOLTAGE (1.24V) ADJUSTABLE PRECISION SHUNT REGULATOR General Description Features Data Sheet BM432(BM431L) The BM432(BM431L) are low voltage three-terminal adjustable regulators with guaranteed thermal stability over a full operation range. These ICs feature sharp turn-on characteristics, low temperature coefficient and low output impedance, which make them ideal substitutes for Zener diodes in applications such as switching power supply, charger, motherboard and other adjustable regulators. The output voltage can be set to any value between 1.24V and 18V with two external resistors. The BM432(BM431L) reference is offered in two bandgap tolerance: 0.5% and 1%. · Wide programmable precise output voltage from 1.24V to 18V · High stability under capacitive load · Low temperature deviation: 3mV typical · Low equivalent full-range temperature coeffi- cient: 20PPM/oC typical · Low dynamic output resistance: 0.05Ω typical · High sink current capacity from 55µA ...
