Regulator
This industry standard linear regulator has the capability to drive
loads up to 400 mA at 5.0, 3.3, 2.5 and 1.8 V. Package options
include DPAK and D2PAK. This device is pin−for−pin compatible
with the Infineon part number TLE4276.
Features
• 5.0, 3.3, 2.5 and 1.8 V; ±4%; Output Voltage at 400 mA
• 500 mV (max) Dropout Voltage
• Inhibit Input
• Very Low Current Consumption
• Fault Protection
♦ +45 V Peak Transient Voltage
♦ −42 V Reverse Voltage
♦ Short Circuit
♦ Thermal Overload
• NCV Prefix for Automotive and Other Applications Requiring Site
and Control Changes
