Precision Voltage Reference
The regulated output voltage depends on the precision
band gap voltage reference in the IC. By adding an error
amplifier into the feedback loop , the output voltage is
maintained within ±4% over temperature and supply
variation.
Output Stage
The composite PNP-
NPN output structure
(Figure 1) provides
300mA (typ) of output
current while maintain-
ing a low drop out volt-
age (1.00V, typ) and
drawing little quiescent
current (2.5mA).
The NPN pass device prevents deep saturation of the out-
put stage which in turn improves the ICs efficiency by
preventing excess current from being used and dissipated
by the IC.
Output Stage Protection
The output stage is protected against overvoltage, short
circuit and thermal runaway conditions (Figure 2).
