PRELIMINARY INFORMATION

50mA ADJUSTABLE CMOS

LDO WITH SHUTDOWN

TC1070

50mA ADJUSTABLE CMOS LDO WITH SHUTDOWN

FEATURES

GENERAL DESCRIPTION

■ Zero Ground Current for Longer Battery Life!

■ Adjustable Output Voltage

■ Very Low Dropout Voltage

The TC1070 is an adjustable LDO designed to super-

cede a variety of older (bipolar) voltage regulators. De-

signed specifically for battery-operated systems, the

TC1070’s CMOS construction eliminates wasted ground

current, significantly extending battery life. Total supply

current is typically 50µA at full load (20 to 60 times lower

than in bipolar regulators!).

■ Guaranteed 50mA Output

■ Power-Saving Shutdown Mode

■ Over-Current and Over-Temperature Protection

■ Space-Saving SOT-23A-5 Package

■

Pin Compatible with LP2980 and MIC5205 Regulators

TC1070 key features include ultra low noise operation

very low dropout voltage (typically 100mV at full load) and

internal feed-forward compensation for fast response to

step changes in load. Supply current is reduced to less than

1µA when the shutdown input is low. The TC1070 incorpo-

rates both over-temperature and over-current protection.

Output voltage is programmed with a simple resistor divider

from V_OUTto ADJ.

The TC1070 is stable with an output capacitor of only

1µF and has a maximum output current of 50mA. For higher

output versions, please see the TC1107, TC1108

(I_OUT= 300mA) data sheets.

APPLICATIONS

■ Battery Operated Systems

■ Portable Computers

■ Medical Instruments

■ Instrumentation

■ Cellular / GSM / PHS Phones

■ Linear Post-Regulator for SMPS

■ Pagers
