General Description
The TC1017 is a high-accuracy (typically ±0.5%)
CMOS upgrade for bipolar low dropout regulators. It is
offered in a SC-70 or SOT-23 package. The SC-70
package represents a 50% reduced footprint versus
the popular SOT-23 package.
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.
With small-space requirements and cost in mind, the
TC1017 was developed to be stable over the entire
input voltage and output current operating range using
low value (1 µF ceramic), low equivalent series
resistance output capacitors. 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 are 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.
