The TLV76033DBZR is a low dropout regulator that implements linear voltage regulation from a wide variety of supply sources. It is ideal for low-noise, low-power applications where the output voltage is tightly regulated. The integrated low dropout voltage design utilizes advanced parasitic-inductance cancellation for low noise performance, improving the efficiency and reducing power consumption.

The TLV76033DBZR integrates a TSSOP-8 footprint with a wide operating voltage range of 1.2V to 6.5V. It also provides low input bias current, as low as 500nA. The output voltage can be an adjustable voltage of 1.2V to 6.5V with an operating junction temperature ranging from -40C to +125C. The regulator also provides low output voltage noise, typically 1μVRMS, combined with an extremely fast transient response, which is beneficial when implementing SMPS solutions and other high-speed applications.

The TLV76033DBZRM integrates a low-dropout voltage, a current limiter, and an over-temperature/current-limit protection circuitry. In case of an overload or over-temperature condition, the regulator will turn off and automatically restart when the voltage returns to a normal operating level. This feature helps to reduce the power dissipation.

The TLV76033DBZRM is ideal for low current applications such as portable electronic equipment, notebook PCs, and automotive systems. It is also suitable for PC card and disk drives. The wide supply voltage range and low input bias current make it an ideal device for applications where a tightly regulated output voltage is needed.

The TLV76033DBZRM of the PMIC - Voltage Regulators - Linear family utilizes a monotonic synchronous rectifier topology, combined with a low dropout linear regulator and a high power-dissipation MOSFET for efficient post-regulating. The integrated synchronous rectifier enables high-efficiency voltage conversion with minimal power dissipation and low EMI potential. The integrated low-dropout linear regulator provides additional current-limiting and overtemperature protection.

The operating principles of the TLV76033DBZRM are based on a two-phase approach. First, a monotonic synchronous rectifier pre-regulates the incoming voltage and then a low-dropout linear regulator provides a precise and stable output voltage, independent of the input voltage level. The MOSFET and the compensation circuitry ensure that the output voltage remains accurate and stable even when the input voltage varies greatly over the specified voltage range.

The TLV76033DBZRM provides excellent performance in a wide variety of applications due to its low dropout voltage, low noise operation and superior transient response. It is also well suited for use in automotive, medical and industrial applications, where low input current and low EMI potential are important design factors.
