NCV4250-2CSNT1G

NCV4250-2C Low Dropout Voltage Tracking Regulator The NCV4250−2C is a monolithic integrated low dropout tracking voltage regulator designed to provide a buffered output voltage that closely tracks the reference input voltage. The part can be used in automotive applications with remote sensors or any situation where it is necessary to isolate the output of the other regulator. The NCV4250−2C also enables the user to bestow a quick upgrade to their module when added current is needed and the existing regulator cannot provide. www.onsemi.com MARKING DIAGRAM 5 TSOP−5 CASE 483 Features • • • • • • • • 5 Up to 50 mA Source Capability Low Output Tracking Tolerance Low Dropout (typ. 120 mV @ 10 mA) Low Quiescent Current in Stand−by Mode Wide Input Voltage Operating Range Protection Features: ♦ Current Limitation ♦ Thermal Shutdown ♦ Reverse Input Voltage and Reverse Bias Voltage AEC−Q100 Grade 1 Qualified and PPAP Capable This is a Pb−Free Device 425AYWG G 1 1 425 A Y W G = Specific Device Code = Assembly Location = Year = Work Week = Pb−Free Package (Note: Microdot may be in either location) PIN CONNECTIONS Typical Applications • Off the Module Loads (e.g. Sensors Power Supply) EN/REF 1 GND 2 Vin 3 5 GND 4 Vout (Top View) ORDERING INFORMATION See detailed ordering and shipping information on page 9 of this data sheet.
