LD39300PT33-R is an integrated circuit (IC) supplied by the company Texas Instruments that is typically employed in power management and voltage regulation applications. The chip is a 3-terminal low dropout regulator (LDO) designed to precisely adjust the operating voltage of a power supply. It is classified in the Texas Instruments\' portfolio of Power Management ICs (PMICs) under Voltage Regulators, more specifically Linear.

At the heart of the LD39300PT33-R LDO are its linear pass element, typically a bipolar transistor, and its voltage reference circuitry. The LDO operates in the direct-substitution mode and implements the linear function Vout = Vref + I x R, where the parameter R represents the effective output impedance of the device from the output terminal to the ground. A simple Current source establishes an adjustable operating current, which is buffered by the LDO to overcome load modulation of the reference voltage. When the input voltage exceeds the reference and the preset minimum, the regulator will reduce the output voltage by modulating the current source bias and maintaining the voltage droop.

This three-terminal voltage regulator can be used in a variety of applications, such as for providing a regulated output voltage to various loads in PC systems, data-acquisition and automotive electronics. This LDO can also be used in space-constrained applications, and its quiescent current helps to reduce standby power consumption and is well-suited to the operation in low power circuits. The LD39300PT33-R is available in the Internally-Equalized three-pin CSOT-8 package and provides excellent thermal performance and minimal parasitic inductance.

The LD39300PT33-R accepts an input voltage of between 4.5 V and 5.5 V, but it has a very low dropout voltage that starts at less than 0.1 V at light load conditions, and up to 1.1 V for up to 1000 mA. It features adjustable output voltage between 1.2 V and 3.3 V and can deliver up to 1 A of output current. It also boasts low noise, fast line/load transient response and high input/output isolation due to its small output impedance of typically 0.22 Ω.

The LD39300PT33-R voltage regulator is designed with the utmost precision to prevent overshoot and undershoot conditions at the output, maximizing system reliability. It implements current-limit protection and provides active-countermeasure (ACM) for reversed input/output terminal connection to protect itself against damage. Furthermore, thermal protection with shut-down and auto-restart allows the device to operate in thermal overload conditions with some restrictions in duty cycle.
