General Description
The TC1269 is a fixed output, high accuracy (typically
±0.5%) CMOS upgrade for older (bipolar) low dropout
regulators. Total supply current is typically 50µA at full
load (20 to 60 times lower than in bipolar regulators).
TC1269 key features include ultra low noise operation
(plus optional Bypass input); very low dropout voltage
(typically 240mV at full load), and fast response to step
changes in load. Supply current is reduced to 0.05µA
(typical) and V
input is low.
The TC1269 incorporates both over temperature and
over current protection. The TC1269 is stable with an
output capacitor of only 1µF and has a maximum
output current of 300mA.
