ULTRA LOW OUTPUT

VOLTAGE LINEAR N-FET

CONTROLLER

DESCRIPTION

The UTC LC1126 is an ultra low output voltage linear N-FET

controller

designed

to

provide

well

supply

voltage

for

front-side-bus termination on motherboards and NB applications.

The UTC LC1126 integrates many functions. A Power-On-Reset

(POR) circuit monitors supply voltages to prevent wrong

operations. A POK indicates the output status with time delay

which is set internally. It can control other converter for power

sequence. It can available for SC-59-6 package.

The UTC LC1126 can be enabled by other power system. A

0.5V

reference

voltage

with

2%

accuracy providing

tight

regulation of the output voltage, enable control, open drain power

good signal, under-voltage protection and soft start.

FEATURES

* MLCC and POSCAP Stable

* 0.5V±2% Reference Voltage

* Internal soft-start

* Enable control

* Fast transient response

* Under-Voltage short circuit protection

* Power OK output with a delay time

* Adjustable output voltage down to 0.5V

* Drive N-Channel MOSFETs
