NCV47701

5 V to 20 V Adjustable Low

Dropout Regulator with

Adjustable Current Limit

The NCV47701 is a 350 mA output current integrated low dropout

regulator designed for use in harsh automotive environments. It

includes wide operating temperature and input voltage ranges. The

device is offered with adjustable voltage versions available in 3%

output voltage accuracy. It has a high peak input voltage tolerance and

reverse input voltage protection. It also provides overcurrent

protection, overtemperature protection and enable for control of the

state of the output voltage. The integrated current sense feature

provides diagnosis and system protection functionality. The current

limit of the device is adjustable by resistor connected to CSO pin.

Voltage on CSO pin is proportional to output current.

Features

• Adjustable Voltage Version (from 5 V to 20 V) ± 3% Output Voltage

for

±6% Output Voltage Accuracy see NCV47700 Specification

• Enable Input (5 V Logic Compatible Thresholds)

for 3.3 V Logic Compatible Thresholds see NCV47710 or

NCV47711 Specification

• Adjustable Current Limit (from 10 mA to 350 mA) with 10%

accuracy

• Protection Features:

♦ Current Limitation

♦ Thermal Shutdown

♦ Reverse Input Voltage

• This is a Pb−Free Device
