Package Type
General Description
The TC1188 and TC1189 are fixed output, low dropout
linear regulators that operate from a 2.7V to 6.0V input
voltage source. The output is capable of delivering up
to 120 mA while consuming only 50 µA of quiescent
current. The low dropout voltage, 120 mV, make the
TC1188 and TC1189 good choices for battery powered
applications. Integrated over-current and over-temper-
ature protection features provide for a fault tolerant
solution.
The TC1189 includes an output voltage auto discharge
feature. When shutdown, the TC1189 will automatically
discharge the output voltage using an internal N-Chan-
nel MOSFET switch.
Fixed output voltage options for the TC1188/TC1189
are: 1.80V, 2.80V, 2.84V and 3.15V. Both the TC1188
and TC1189 are available in SOT23-5 packages.
