General Description
The TC1016 is a high-accuracy (typically ±0.5%),
CMOS upgrade for bipolar low dropout regulators
(LDOs). The TC1016 is offered in both the SC-70 and
SOT-23 packages. The SC-70 package represents a
50% footprint reduction versus the popular SOT-23
package.
Developed specifically for battery-powered systems,
the device’s CMOS construction consumes only 53 µA
typical supply current over the entire 80 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
TC1016 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 (ESR) output capacitors. Additional
integrated features (such as shutdown, overcurrent
and overtemperature protection) further reduce board
space and cost of the entire voltage-regulating
application.
Key performance parameters for the TC1016 are low
drop out voltage (150 mV (typ.) at 80 mA output
current), low supply current while shutdown (0.05 µA
typical) and fast stable response to sudden input
voltage and load changes.
