onsemi Voltage Regulator Surface Mount Positive Polarity 20V 3-Pin NCV1117DT18T5G

onsemi NCV1117DT18T5G is a surface mount positive polarity low dropout (LDO) voltage regulator designed to deliver output currents exceeding 1A. Its compact form factor with exact dimensions of 6.73mm by 6.22mm by 2.38mm suits modern electronics assembly techniques. With a maximum input voltage rating of 20V, it supports a wide range of power management applications including automotive use under the AEC-Q100 standard.

This device features an improved dropout voltage of up to 1.2V at 800mA over temperature, ensuring efficient power conversion with reduced dissipation. It integrates current limit and thermal shutdown circuitry to protect the device and surrounding components from damage due to overload or overheating. The quiescent current is typically 10mA, helping to conserve energy in low-power designs.

The NCV1117DT18T5G does not require a minimum load to maintain stable regulation, facilitating simplified power system designs. Fixed voltage options eliminate the need for external programming, while adjustable versions allow output voltages programmable from 1.25 to 18.8 V, increasing flexibility.

Applications include consumer and industrial electronic equipment such as active SCSI termination, switching power supply post regulation, hard drive controllers, and battery chargers. Its robustness and automotive-grade approval make it a reliable choice for critical systems requiring stringent quality standards.

Output current capability exceeds 1A for broad application. 1.2V maximum dropout voltage at 800mA providing efficient operation. Includes current limit and thermal shutdown for protection. Automotive qualified under AEC-Q100 standard.
