TC1017

150 mA, Tiny CMOS LDO With Shutdown

Features

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.
