Package Type

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 50

µAat 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 0.05

µA

(typical) and VOUT falls to zero when the shutdown

input is low.

The TC1269 incorporates both over temperature and

over current protection. The TC1269 is stable with an

output capacitor of only 1

µF and has a maximum

output current of 300mA.
