The ZLDO1117G33TA is a low-dropout (LDO) linear regulator designed to supply board mount circuits. It is a fixed voltage regulator with a typical voltage drop of 1.17V and an input voltage range of 2V to 20V.

The ZLDO1117G33TA is a member of the PMIC – Voltage Regulators – Linear category and offers a high-performance, drop-in solution for a broad range of linear regulators that supply power to consumer electronics and industrial applications.

The ZLDO1117G33TA is available in a 8-lead SOT-23 surface mount package and has a quiescent current range of 2.5mA to 9.5mA with up to 35mA of output current. The device features a sink/source current of 0.4mA/1mA and an on/off control for power management. It also has an inrush-limiting current limit of 6A, thermal shutdown protection, and an output voltage leveling of ±1.5%.

The ZLDO1117G33TA offers high power efficiency and stability with its low dropout voltage, meaning that it can remain stable even under extreme load conditions. Its low dropout voltage also makes it an ideal choice for applications that require a low drop-in voltage, such as in portable devices. The device is also designed to have a low noise output and fast transient response time.

The ZLDO1117G33TA output voltage is adjusted by a single external resistor and its typical output voltage is determined by the input voltage, the output voltage and the external resistor. The working principle of the LDO is straightforward and it is designed to have a symmetrical topology that provides a low output impedance to minimize output voltage variation due to load current variation. The ZLDO1117G33TA also incorporates a short-circuit protection scheme that reduces the available current to prevent incorrect operations or device damage.

The ZLDO1117G33TA is ideal for applications in telecommunications, computer, consumer, industrial and medical equipment, automotive and networking systems, point-of-load converters, and other applications that require a stable power supply. It is also suitable for outdoor units, where its low dropout voltage enables it to operate at a lower input voltage. With its high reliability, the device is also suitable for applications that require a high level of reliability and stability.
