一,产品概述(General Description)

The JTMA1206 family of devices are ultra low dropout 1A regulators using PNP transistor
as the pass element.These products are ideal when a single input supply is only available and
the dropout voltage is less than 1V,exceeding the minimum dropout characteristics of NPN/
PNP hybrid regulators. One common application of these regulators is where input is 3.3V
and a 2.5V output is needed.
Besides the low dropout of less than 0.5V, other fea-tures of the family of the parts are:
micro-power shut-down capability and output UVLO detection where Flag pin is switched low
when output is below 5% of its nomi-nal point.
