The TC1017 is a high-accuracy (typically ±0.5%)
CMOS upgrade for bipolar Low Dropout regulators
(LDOs). It is offered in a SC-70 or SOT-23 package.
The SC-70 package represents a 50% footprint reduction
versus the popular SOT-23 package and is offered
in two pinouts to make board layout easier.
Developed specifically for battery-powered systems,
the TC1017’s CMOS construction consumes only
53 μA typical supply current over the entire 150 mA
operating load range. This can be as much as 60 times
less than the quiescent operating current consumed by
bipolar LDOs.
The TC1017 is designed to be stable, over the entire
input voltage and output current range, with low-value
(1 μF) ceramic or tantalum capacitors. This helps to
reduce board space and save cost. Additional integrated
features, such as shutdown, overcurrent and
overtemperature protection, further reduce the board
space and cost of the entire voltage-regulating
application.
Key performance parameters for the TC1017 include
low dropout voltage (285 mV typical at 150 mA output
current), low supply current while shutdown (0.05 μA
typical) and fast stable response to sudden input
voltage and load changes.
