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

(LDOs). It is offered in a SC-70 or SOT-23 package.

The SC-70 package represents a 50% footprint reduc-

tion versus the popular SOT-23 package and is offered

in two pinouts to make board layout easier.

• Space-saving 5-Pin SC-70 and SOT-23 Packages

• Extremely Low Operating Current for Longer

Battery Life: 53 µA (typ.)

• Very Low Dropout Voltage

• Rated 150 mA Output Current

• Requires Only 1 µF Ceramic Output Capacitance

• High Output Voltage Accuracy: 0.5% (typical)

• 10 µs (typ.) Wake-Up Time from SHDN

• Power-Saving Shutdown Mode: 0.05 µA (typ.)

• Overcurrent and Overtemperature Protection

• Pin-Compatible Upgrade for Bipolar Regulators

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 inte-

grated features, such as shutdown, overcurrent and

overtemperature protection, further reduce the board

space and cost of the entire voltage-regulating

application.

Applications:

• Cellular/GSM/PHS Phones

• Battery-Operated Systems

• Portable Computers

• Medical Instruments

• Electronic Games

• Pagers

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.
