TC1300

300 mA CMOS LDO with Shutdown, Bypass and

Independent Delayed Reset Function

Features

General Description

• LDO with Integrated Microcontroller Reset

Monitor Functionality

The TC1300 combines a low dropout regulator and a

microcontroller reset monitor in an 8-Pin MSOP pack-

age. Total supply current is 80 µA (typical), 20 to 60

times lower than bipolar regulators.

• Low Input Supply Current (80 µA, typical)

• Very Low Dropout Voltage

The TC1300 has a precise output with a typical accu-

racy of ±0.5%. Other key features include low noise

operation, low dropout voltage and internal feed-

forward compensation for fast response to step

changes in load. The TC1300 has both over-tempera-

ture and over-current protection. When the shutdown

control (SHDN) is low, the regulator output voltage falls

to zero, RESET output remains valid and supply cur-

rent is reduced to 30 µA (typical). The TC1300 is rated

for 300 mA of output current and stable with a 1 µF out-

put capacitor.

• 10 µsec (typ.) Wake-Up Time from SHDN

• 300 mA Output Current

• Standard or Custom Output and Detected

Voltages

• Power-Saving Shutdown Mode

• Bypass Input for Quiet Operation

• Separate Input for Detected Voltage

• 140 msec Minimum RESET Output Duration

• Space-Saving MSOP Package

• Specified Junction Temperature Range:

-40°C to +125°C

An active-low RESET is asserted when the detected

voltage (V_DET) falls below the reset voltage threshold.

The RESET output remains low for 300 msec (typical)

after V_DETrises above reset threshold. The TC1300

also has a fast wake-up response time (10 µsec.,

typical) when released from shutdown.

Applications

• Battery-Operated Systems

• Portable Computers

• Medical Instruments

• Pagers

• Cellular / GSM / PHS Phones
