EZ1117CSTTRT

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The EZ1117CSTTRT is an adjustable positive low-dropout (LDO) voltage regulator manufactured by Semtech. It operates within an input voltage range of 2.65 V to 7 V and delivers a maximum output current of 800 mA. The device provides an adjustable output voltage between 1.3 V and 5.7 V, utilizing a 1.25 V reference voltage with a tolerance of 2%. Key electrical characteristics include a typical power supply rejection ratio (PSRR) of 72 dB, a maximum dropout voltage of 1.2 V, line regulation of 0.035%, and load regulation of 0.2%. It is housed in a surface-mount SOT-223-3 package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify component authenticity through authorized channels as this part number is listed as obsolete or end-of-life by the manufacturer. Confirm specific revision codes and packaging details directly with suppliers, as availability may be limited to existing stock or last-time buy options. Ensure compatibility with RoHS requirements if applicable to your manufacturing standards.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when an adjustable LDO with 800 mA capacity is required in a compact SOT-223-3 package. It is suitable for applications where input voltages do not exceed 7 V and output stability is critical. Consider thermal dissipation capabilities given the package size and current rating. Compare against fixed-voltage alternatives if the application does not require adjustability.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This device belongs to the EZ1117C series of low-dropout regulators from Semtech. It shares functional similarities with other parts in the family but is distinguished by its specific SOT-223-3 packaging and adjustable output range. The series is designed for general-purpose power management tasks requiring moderate current handling and high line regulation performance.
